- About Good
- The grade AG-3. The grade of a coin that falls short of Good. Only the
main features of the coin are present in this grade. Peripheral lettering,
date, stars, etc. sometimes are partially worn away.
- About Uncirculated
- Alternate of Almost Uncirculated.
of a coin where a foreign object or another coin has displaced metal
in an abraded fashion. Similar to a bag mark but usually on the high
points or open fields and not as deep or acute as the former.
miscellaneous grouping of coins, often as a monetary hoard. Opposite
of a coin collection. A second use is as a grouping of a particular
date, type, or series. (Example: an accumulation-of Bust Halves.)
file marks seen mainly on gold and silver coins prior to 1840. These
removed excess metal from overweight planchets. After 1840 these are
seldom seen as the filing was on the rim and was usually obliterated
by the striking process.
is for "About Good" (the grade) and "3" (the corresponding numerical
designation). Most of the lettering on the coin is readable, but there
is moderately heavy wear into the rims. This grade is frequently found
on Standing Liberty Quarters coins where the obverse is fully Good
(or better) but the reverse is heavily worn.
to album slide marks, though the friction may be only slight rubbing
on the high points. Album friction is very common on coins with high
relief designs. For example Walking Liberty Half Dollars in Choice
Unicirculated can be found with very minor friction on the hips of
Miss Liberty. Another example of this friction can be found on the
knee and leg of many Unicirculated examples of Standing Liberty Quarters.
Better to look for coins without this problem.
usually parallel, imparted to the surface of a coin by the plastic
"slide" of Whitman Coin albums. Walking Liberty Half Dollars in Choice
Unicirculated can be found with very minor friction on the hips of
Miss Liberty. Another example of this friction can be found on the
knee and leg of many Unicirculated examples of Standing Liberty Quarters.

combination of two or more metals.
grades AU50, 53, 55, and 58. A coin that on first glance appears Uncirculated
but upon closer inspection has slight friction or rub.
coin that has a date, mint mark, or other feature that has been changed,
added, or removed, usually to simulate a rarer issue.
non-profit numismatic organization founded in 1888 for the advancement
for "American Numismatic Association."

only authentication was offered, grading was added later. The grading
service and acronym were sold by the ANA and now operate under this
name as a third party grading service.
uniquely numbered opinion of authenticity and/or grade from the ANA
Certification Service. The ANA now only authenticates, having sold
the name and grading service. Old ANACS certificates that include
the grade of the coins should be considered highly unreliable. The
grading certification program saw major swings in the grading standard.
As a result many coins graded by ANACS from 1980 through 1988 were
term for coins of the world struck circa 600 B.C. to circa 450 A.D.
- The heating of a die or planchet to soften the
metal before preparation of the die or striking of the coin.
lower die, usually the reverse - although on some issues with striking
problems, the obverse was employed as the lower die. Because of the
physics of minting, the fixed lower-die impression is slightly better
struck than the upper-die impression.
- Design element usually found in the left (viewer's
right) claw of the eagle seen on many United States coins. After 1807,
there usually were three arrows while prior to that time the bundle
consisted of numerous ones.
- Term referring to the quarters and half dollars
of 1853. The rays were removed in 1854 because of striking difficulties
presented by the busy design.
- arrows at date
- Term referring to the arrows to the left and right of the date, added to the dies to
indicate a weight increase or decrease.
- artificial toning
- Coloring added to the surface of a coin by chemicals and/or heat. Many different
methods have been employed over the years.
- The selling quotation of a coin either on a trading network, pricing newsletter, or
- The elements that make up a coin's grade. The main ones are marks (hairlines for
Proofs), luster, strike, and eye appeal.
- This is for "About Uncirculated" (the grade) and "50" (the numerical designation
of that grade). Also called "Almost Uncirculated-50." This is the lowest of the
four AU grades, with the others being AU53, AU55, and AU58. Between 50%
and 100% of the surfaces will exhibit luster disturbances, and perhaps the only
luster still in evidence will be in the protected areas. The high points of the coin
will have wear that is easily visible to the naked eye.
- This is for "About Uncirculated" (the grade) and "53" (the numerical designation
of that grade). Also called "Almost Uncirculated-53." There is obvious wear on
the high points with light friction covering 50-75% of the fields. There are
noticeable luster breaks, with most of the luster still intact in the protected areas.
- This is for "About Uncirculated" (the grade) and "55" (the numerical designation
of that grade). Also called "Almost Uncirculated-55." There is slight wear on the
high points with minor friction in the fields. Luster can range from almost
nonexistent to virtually full, but it will be missing from the high points. The grade
of "Choice AU" equates to AU55.
- This is for "About Uncirculated" (the grade) and "58" (the numerical designation
of that grade). Also called "Almost Uncirculated-58." There is the slightest wear
on the high points, even though it may be necessary to tilt the coin towards the
light source to see the friction. In many cases the reverse of an AU58 coin will be
fully Mint State. Less than 10% of the surface area will show luster breaks. The
grade of "Borderline Unc" equates to AU58.

have been incurred in a bag.
- bag toning
- Coloring acquired from the bag in which a coin was stored. The cloth bags in
which coins were transported contained sulfur and other reactive chemicals.
When stored in such bags for extended periods, the coins near and in contact with
the cloth often acquired beautiful red, blue, yellow and other vibrant colors.
Sometimes the pattern of the cloth is visible in the toning; other times, coins have
crescent-shaped toning because another coin was covering part of the surface,
preventing toning. Bag toning is seen mainly on Morgan silver dollars, though
occasionally on other series.
- Bank-wrapped rolls
- Rolls of coins that were wrapped at a Federal Reserve Bank from original Mint
bags. Such rolls are often desirable to collectors because they have not been
searched or "picked" by collectors or dealers. Sometimes abbreviated as OBW,
for "original bank wrapped."

- The value base from which Dr. William H. Sheldon's 70-point grade/price system
started; this lowest-grade price was one dollar for the 1794 large cent upon which
he based his system.
- The process of polishing a die to impart a mirrored surface or to remove clash
marks or other injuries from the die.

- A blue-cover, wholesale pricing book for United States coins issued on a yearly
basis. Dealers used it from the late 1940's through the 1970's and collectors as a
guide in determining the prices they would pay to collectors for rare coins. It is
largely out of use for the purpose and has been supplanted almost entirely by the
Coin Dealer Newsletter's publications and online computer networks.
- Slang for the Certified Coin Dealer Newsletter.
- The designation BM refers to "Branch Mint," meaning any US Mint other than

- breast feathers
- The central feathers seen on numerous eagle designs. Fully struck coins usually
command a premium and the breast feathers are usually the highest point of the
reverse. (They are the most deeply recessed area of the die, so metal sometimes
does not completely fill the breast feather area, usually because of insufficient
striking pressure. Incorrectly spaced or lapped dies will also cause "striking"
- Slang for the late Walter Breen. Often heard in context of Breen letter, Breen said,
Breen wrote, and so on. Walter Breen's personal life dimmed the impact he had

seizure by the Confederacy. (Those coins struck in late 1837 were dated 1838.)
- cabinet friction
- Slight disturbance seen on coins (usually on the obverse) that were stored in
wooden cabinets used by early collectors to house their specimens. Often a soft
cloth was used to wipe away dust, causing light hairlines or friction. Europeans in

coins are especially difficult because of this problem.
- Short for Cameo. Also, PCGS grading suffix used for 1950 and later Proofs that
meet cameo standards.
- The term applied to coins, usually Proofs and prooflike coins, that have frosted
devices and lettering that contrast with the fields. When this is deep the coins are
said to be "black and white" cameos. Occasionally frosty coins have "cameo"
devices though they obviously do not contrast as dramatically with the fields as
the cameo devices of Proofs do. Specifically applied by PCGS to those 1950 and
later Proofs that meet cameo standards (CAM).

credited to John Reich.
- capped die
- The term applied to an error in which a coin gets jammed in the coining press and
remains for successive strikes, eventually forming a "cap" either on the upper or
lower die. These are sometimes spectacular with the "cap" often many times taller
than a normal coin.
- carbon spot
- A spot seen mainly on copper and gold coins, though also occasionally found on
U.S. nickel coins (which are 75 percent copper) and silver coins (which are 10
percent copper). Carbon spots are brown to black spots of oxidation that range
from minor to severe -- some so large and far advanced that the coin is not graded
because of environmental damage. The natural oil from your hands, tiny spit that
gets sprayed when speaking around unprotected copper and nickel coins can
cause carbon spots. Be warned, be careful.
- Carson City
- The United States branch Mint located in Carson City, Nevada that struck coins
from 1870 until 1885 and again from 1889 until 1893. These are among the most

Barber, Morgan, etc. are examples of designs.
- design type
- A specific motif placed upon coinage which may be used for several
denominations and subtypes, e.g., the Liberty Seated design type used for silver
coins from half dimes through dollars and various subtypes therein.
- The individual responsible for a particular motif used for a numismatic series.
- Any specific design element. Often refers to the principal design element, such as
the head of Miss Liberty.
- device punch
- A steel rod with a raised device on the end used to punch the element into a
working die. This technique was used before hubbed dies became the norm.
- A steel rod that is engraved, punched, or hubbed with devices, lettering, the date,
and other emblems.
- die alignment
- Term to indicate the relative position of the obverse and reverse dies. When the
dies are out of alignment, several things can happen: If the dies are out of parallel,
weakness may be noted in a quadrant of the coin's obverse and the corresponding
part of the reverse; and if the dies are spaced improperly, the resultant coins may
have overall weakness; if the dies are spaced too close together, the resultant coin
may be well struck but the dies wear more quickly.
- die break
- An area of a coin that is the result of a broken die. This may be triangular or other
geometric shape. Dies are made of steel and they crack from use and then, if not
removed from service, eventually break. When the die totally breaks apart, the
resultant break will result in a full, or retained, cud depending whether the broken
piece falls from the die or not.
- die crack
- A raised, irregular line on a coin, ranging from very fine to very large, some quite
irregular. These result when a hairline break occurs in a die.
- die line
- These are the raised lines on the coins that result from the polish lines on the die,
which are incuse, resulting in the raised lines on the coins.
- die rust
- Rust that has accumulated on a die that was not stored properly. Often such rust
was polished away, so that only the deeply recessed parts of the die still exhibited
it. A few examples are known of coins that were struck with extremely rusted dies
-- the 1876-CC dime, for one.
- die state
- A readily identified point in the life of a coinage die. Often dies clash and are
polished, crack, break, etc., resulting in different stages of the die. These are
called die states. Some coins have barely distinguishable die states, while others
go through multiple distinctive ones.
- die striations
- Raised lines on coins that were struck with polished dies. As more coins are
struck with such dies, the striations become fainter until most disappear.
- die trial
- A test striking of a particular die in a different metal.
- die variety
- A coin that can be linked to a given set of dies because of characteristics
possessed by those dies and mparted to the coin at the time it was struck. In the
early years of U.S. coinage history, when dies were made by hand engraving or
punching, each die was slightly different. The coins from these unique dies are die
varieties and are collected in every denomination. By the 1840's, when dies were
made by hubbing and therefore were more uniform, die varieties resulted mainly
from variances in the size, shape, and positioning of the date and mintmark.
- die wear
- Deterioration in a die caused by excessive use. This may evidence itself on coins
produced with that die in a few indistinct letters or numerals or, in extreme cases,
a loss of detail throughout the entire coin. Some coins, especially certain nickel
issues, have a fuzzy, indistinct appearance even on Uncirculated examples.
- The denomination, one tenth of a dollar, issued since 1796 by the United States.
- A term applied to a coin that has been placed in a commercial "dip" solution, a
mild acid wash that removes the toning from most coins. Some dip solutions
employ other chemicals, such as bases, to accomplish a similar result. The first
few layers of metal are removed with every dip, so coins repeatedly dipped will
lose luster, hence the term "overdipped".
- dipping solution
- Any of the commercial "dips" available on the market, usually acid-based.
- The original spelling of dime, the s silent and thought to have been pronounced to
rhyme with steam. (This variation was used in Mint documents until the 1830s
and was officially changed by the Coinage Act of 1837.)
- Short for deep mirror prooflike.
- Term used for a numismatic item that has been enhanced by chemical or other
means. Usually, this is used in a derogatory way.
- The denomination, consisting of one hundred cents, authorized by the Mint Act of
1792. This is the anglicized spelling of the European Thaler and was used because
of the world-wide acceptance of the Thaler and the Spanish Milled dollar or
- Double Eagle
- Literally two eagles, or twenty dollars. A twenty-dollar U.S. gold coin issued
from 1850 through 1932. One gold double eagle dated 1849 is known and is part
of the National Numismatic Collection at the Smithsonian Institution. Nearly half
a million examples dated 1933 were struck by the U.S. Mint, but virtually all were
melted when private gold ownership was outlawed that year. (Recently the only
legal to own specimen of the 1933 $20 Double Eagles sold for $7.59 Million. It's
now considered the most famous rare coin in the world)
- double(d) die
- A die that has been struck more than once by a hub in misaligned positions,
resulting in doubling of design elements. Before the introduction of hubbing, the
individual elements of a coin's design were either engraved or punched into the
die, so any doubling was limited to a specific element. With hubbed dies, multiple
impressions are needed from the hub to make a single die with adequate detail.
When shifting occurs in the alignment between the hub and the die, the die ends
up with some of its features doubled -- then imparts this doubling to every coin it
strikes. The coins struck from such dies are called doubled-die errors -- the most
famous being the 1955 Doubled Die Lincoln cent. PCGS uses doubled die as the
- Slang for the rare 1955 Doubled Die Lincoln Cent variety.
- A condition that results when a coin is not ejected from the dies and is struck a
second time. Such a coin is said to be double-struck. Triple-struck coins and other
multiple strikings also are known. Proofs are usually double-struck on purpose in
order to sharpen their details; this is sometimes visible under magnification.
- Short for deep mirror prooflike.
- Draped Bust
- The design attributed to Mint engraver Robert Scot that features Miss Liberty
with a drape across her bust. Scot presumably copied the design after a portrait by
- drift mark
- An area on a coin, often rather long, that has a discolored, streaky look. This is
the result of impurities or foreign matter in the dies. One theory is that burnt wood
was rolled into the strips from which the planchets were cut, resulting in these
- Term for a numismatic item that is lack luster. This may be the result of cleaning,
oxidation, or other environmental conditions.
- Short for Early American Coppers
- A gold coin with a face value of ten dollars. Along with the dollar, this was the

struck for circulation after 1933, and all gold coins issued prior to that time were
recalled from circulation.

or water which has severely pitted surfaces. PCGS does not grade coins with
- eroded die
- Synonym for "worn die."
- A numismatic item that unintentionally varies from the norm. Ordinarily,
overdates are not errors since they were done intentionally while other die-cutting

etc. also are errors.
- Term for trial, pattern, and experimental strikings. The anglicized version is essay

- Extremely High Relief
- The 1907 double eagle issue by Augustus Saint-Gaudens that had such medallic
depth that multiple blows from a powerful press were required to fully bring up
the detail. Because of this difficulty, the Mint engraver lowered the design
resulting in the High Relief, which again was lowered to create the familiar
Standing Liberty double eagle, or Saint, as to which they are commonly referred.
- eye appeal
- The element of a coin's grade that "grabs" the viewer. The overall look of a coin.
- This is for "Fine" (the grade) and "12" (the numerical designation of the grade).

- This has two meanings. First, it is the term for the plastic sleeve in which coins
are stored. Also, it can mean to quickly sell a recently purchased coin, usually for
a short profit. (The plastic flips used to submit coins to PCGS are not
recommended for long term storage unless they do not contain PVC. Care should
be used with the PVC-free flips as they are very brittle and can damage the
delicate coin surfaces).
- flip rub
- Discoloration, often only slight, on the highest points of a coin resulting from
contact with a flip. On occasion, highly desirable coins sold in auctions have
acquired minor rub from being repeatedly examined by eager bidders. The
shifting of the coin, although it may be slight, can cause this rub.
- To sell a new purchase for a short profit.

- Short for Full Steps.
- Fugio cents
- These 1787-dated one-cent coins are considered by some to be the first regular
issue United States coin. Authorized by the Continental Congress, this would
seem to be a logical conclusion. However, the Mint Act was not passed by
Congress until 1792, so the case for the half dismes of 1792 as the first regular
issue is also valid. (Adam Eckfeldt, Chief Coiner from 1814 to 1839 worked for
the fledgling Mint in 1792 and was present for the striking of the 1792 half
dismes. He is quoted in the 1840s that he considered the half dismes patterns and
that George Washington gave them out as presents. He was a very old man by
then, so perhaps his memory was failing him, but debate continues as to which
coin deserves the distinction as the first regular issue. If the half disme and the
Fugio cent are not the first coins, then that title would go to the Chain cent, which
was the first coin struck in the newly occupied Mint building. Although the
building was likely occupied in late 1792, as records indicate, it appears that all
the machinery was not fully operational as Chain cents were not struck until

- Key Coin
- The major, or most important, coin in a particular series. The "key" coin is usually
the lowest-mintage coin and/or the most expensive coin in a particular set. The
1916-D dime, for instance, is usually considered the key coin of the Mercury
dime series. It is the lowest mintage coin of the set and the most expensive (in
most grades). The 1919-D dime is the "condition rarity key" of the Mercury dime
series, as it is the most expensive coin in top condition.
Most sets have more than one key coin. In Lincoln cents, for instance, the 1909-S
V.D.B., the 1914-D, the 1922 Plain and 1955/55 Doubled Die are all considered
to be key coins in most grades. In MS65RD the 1926-S is the rarest of the regular
issues, so it is considered the "condition rarity key."
At times any scarce or rare coin is referred to a "key" coin. The terms "key to the
set" or "key to the series" are also used as synonyms for "key coin."

- lettered edge
- A coin edge that displays an inscription or other design elements, rather than
being reeded or plain. The lettering can be either incuse (recessed below the
surface) or raised. Incuse lettering is applied before a coin is struck; the Mint did
this with a device called the Castaing machine. Raised lettering is found on coins
struck with segmented collars; the lettering is raised during the minting process,
and when the coin is ejected from the dies, the collar "falls" apart, preventing the
lettering from being sheared away.

denote a business strike coin that never has been in circulation. A Mint State coin
can range from one that is covered with marks (MS-60) to a flawless example
- The number of coins of a particular date struck at a given mint during a particular
year. (This may not equal the "official" mintage for that calendar year, especially
for pre-1840 coinage. The Mint reported coins struck in the calendar year,
regardless of the date(s) on the issue. For instance, the 1804-dated dollar was
included in Proof Sets struck in 1834 because the "official" mintage figures for
1804 included silver dollars although it is now known that these were dated 1803
or possibly even earlier.)

- mottled toning
- Uneven toning, usually characterized by splotchy areas of drab colors.
- An inscription on a coin -- especially IN GOD WE TRUST, which first appeared
on the 1864 two-cent piece andnow is required on all U.S. coinage.
- This is for "Mint State" (the grade) and "60" (the numerical designation of that
grade). This is the lowest of the eleven Mint State grades that range from MS60
through MS70. An MS60 coin will usually exhibit the maximum number of
marks and/or hairlines. The luster may range from poor to full, but is usually on
the "poor" side. Eye appeal is usually minimal.
- This is for "Mint State" (the grade) and "61" (the numerical designation of that
grade). This grade meets the minimum requirements of Mint State plus includes
some virtues not found on MS60 coins. For instance, there may be slightly fewer
marks than on an MS60 coin, or better luster, or less negative eye appeal.
- This is for "Mint State" (the grade) and "62" (the numerical designation of that
grade). This grade is nearly in the "choice" or MS63 category, but there is usually
one thing that keeps it from a higher grader. Expect to find excessive marks or an
extremely poor strike or dark and unattractive toning. Some MS62 coins will have
clean surfaces and reasonably good eye appeal but exhibit many hairlines on the
fields and devices.
- This is for "Mint State" (the grade) and "63" (the numerical designation of that
grade). The equivalent of "choice" or "Choice BU" from the days before
numerical grading was prevalent. This grade is usually found with clean fields
and distracting marks or hairlines on the devices OR clean devices with
distracting marks or hairlines in the fields. The strike and luster can range from
mediocre to excellent.
- This is for "Mint State" (the grade) and "64" (the numerical designation of that
grade). This grade is also called "Borderline Gem" at times, as well as "Very
Choice BU." There will be no more than a couple of significant marks or,
possibly, a number of light abrasions. The overall visual impact of the coin will be
positive. The strike will range from average to full and the luster breaks will be
- This is for "Mint State" (the grade) and "65" (the numerical designation of that
grade). This grade is also called "Gem" or "Gem Mint State" or "Gem BU." There
may be scattered marks, hairlines or other defects, but they will be minor. Any
spots on copper coins will also be minor. The coin must be well struck with
positive (average or better) eye appeal. This is a NICE coin!
- This is for "Mint State" (the grade) and "66" (the numerical designation of that
grade). This is not only a Gem-quality coin, but the eye appeal ranges from
"above average" to "superb." The luster is usually far above average, and any
toning can not impede the luster in any significant way. This is an extra-nice coin.
- This is for "Mint State" (the grade) and "67" (the numerical designation of that
grade). A superb-quality coin! Any abrasions are extremely light and do not
detract from the coin's beauty in any way. The strike is extremely sharp (or full)
and the luster is outstanding. This is a spectacular coin!
- This is for "Mint State" (the grade) and "68" (the numerical designation of that
grade). A nearly perfect coin, with only minuscule imperfections visible to the
naked eye. The strike will be exceptionally sharp and the luster will glow. This is
an incredible coin.
- This is for "Mint State" (the grade) and "69" (the numerical designation of that
grade). Virtually perfect in all departments, including wondrous surfaces, a 99%
full strike (or better), full unbroken booming luster and show-stopping eye appeal.
You may have to study this coin with a 5X glass to find the reason why it didn't
- This is for "Mint State" (the grade) and "70" (the numerical designation of that
grade). A perfect coin! Even with 5X magnification there are no marks, hairlines
or luster breaks in evidence. The luster is vibrant, the strike is razor-sharp, and the
eye appeal is the ultimate. Note: Minor die polish and light die breaks are not
considered to be defects on circulation strike coins.
- Mule Error
- This is a rare Mint error where the obverse die is of one coin and the reverse die is
of another coin. The most famous of the Mule errors is a Sacagawea
dollar/Washington quarter Mule, where a Washington quarter obverse is paired

had arrows by the date. (Example: the 1853 No Arrows half dime and 1853
Arrows half dime.)
- No Motto
- Coins struck without the motto, "IN GOD WE TRUST." This motto was
mandated by an act of Congress and appeared on nearly every United States coin
since the 1860s. (Teddy Roosevelt felt this was sacrilegious and had it removed
from the newly redesigned 1907 eagles and double eagles. Citizen protests soon
were overwhelming and it was restored in 1908.) This also refers to coins struck
before the motto was added in the 1860s.
- No Stars
- Term applying to the Christian Gobrecht designed Liberty Seated coins without
- No "CENTS" nickel
- Those Liberty Head or "V" nickels struck in 1883 without a denomination. This

- off center
- A coin struck on a blank that was not properly centered over the anvil, or lower,
die. Coins that are 5 percent, or less, off center are graded by PCGS as a regular
coin. Those struck off center more than 5 percent are graded as error coins. There
will be an "E" before the coin number to designate an error specimen and the
amount struck off center will be listed, rounded to the nearest 5 percent.
- open collar
- Its name notwithstanding, a closed collar that surrounded the anvil (or lower) die
used in striking early U.S. coins on planchets whose edges already had been
lettered or reeded. An open collar was a restraining, or positioning, collar that
made it easier to position a planchet atop the lower die, and also sometimes kept
the planchet from expanding too far.

nickels, 50 dimes, 40 quarters, 20 half dollars and 20 silver dollars. U.S. coins
were first shipped to banks in kegs, later in cloth bags, and still later in rolls.
Silver and gold coins stored in such rolls often have peripheral toning and
untoned centers. Obviously, coins stored in rolls suffered fewer marks than those
in kegs or bags.
- Original rolls
- Rolls of coins that have been together since the day they were removed from their
storage bags. Also, rolls of Mint State coins that have never been searched or
- Original skin

Uncirculated coins are the only coins that can have their original skin. Bagmarks
do not necessarily mean that a rare coin doesn't have its original skin.
- original toning
- Term for the color acquired naturally by a coin that never has never been cleaned
or dipped. Original toning ranges from the palest yellow to extremely dark blues,
grays, browns, and finally black.
- over -mintmark
- A coin struck with a die on which one mintmark is engraved over a different
mintmark. In rare instances, branch mints returned dies that already had
mintmarks punched into them; on occasion, these were then sent to different
branch mints and the new mint punched its mintmark over the old one. Examples
include the 1938-D/S Buffalo nickel and the 1900-O/CC Morgan dollar.
- over dipped
- A coin that has become dull from too many baths in a dipping solution.
- A coin struck from a die with a date that has one year punched over a different

were the best available protection for the coin buyer. Each PNG dealer could issue
a certificate, one copy given to the buyer and one copy sent to the PNG main
office. This provided not only a guarantee of authenticity, but also provided a
space for a description that could be useful in cases of stolen collections.
- This is for "Poor" (the grade) and "1" (the numerical designation that means
Poor). A coin of this grade is basically uncollectible due to its terrible condition,

and in demand in this grade. In order to "reach" this grade a coin must be
identifiable as to date and type and not be horribly damaged (such as holes).

- A coin usually struck from a specially prepared coin die on a specially prepared
planchet. Proofs are usually given more than one blow from the dies and are
usually struck with presses operating at slower speeds and higher striking
pressure. Because of this extra care, Proofs usually exhibit much sharper detail
than regular, or business, strikes. PCGS recognizes Proofs (PR) as those struck in
1817 and later. Those coins struck prior to 1817 are recognized as Specimen
- Proof set

anomalies such as the 1804 dollar and eagle in 1834 presentation Proof sets.
- Proof dies
- Specially prepared dies, often sandblasted or acid-picked, that are used to strike
Proof coins. Often, the fields are highly polished to a mirrorlike finish, while the

frosted and contrast with highly reflective fields. Matte, Roman, and Satin Proof
dies are not polished to a mirror-like finish.
- Proof-only issue
- A coin struck only in Proof, with no business-strike counterpart.

gold piece since the V on the reverse could be interpreted as either five cents or
five dollars! (They have also been gold-plated since that time to sell to collectors.)

- repunched date
- If a date was punched into the die and then punched in again in a different
position it is considered to be a repunched date. A dramatic example of the
repunched date is the 1894/94 Indian cent, where the two dates are clear, bold and
well separated. Most repunched dates are more subtle, such as the 1887/6 Morgan
dollar. Such coins as the 1909/8 $20 gold piece or the 1942/1 Mercury dime are
not repunched dates, but Doubled Dies, where the changes were made to the
working die from a differently-dated working hub.
- A coin struck later than indicated by its date, often with different dies.
Occasionally, a different reverse design is used, as in the case of restrike 1831

- Term for a mark or indentation on the rim of a coin or other metallic numismatic
- ring test
- A test used to determine whether a coin was struck or is an electrotype or cast
copy. The coin in question is balanced on a finger and gently tapped with a metal
object- a pen, another coin, and so on. Struck coins have a high-pitched ring or
tone, while electrotypes and cast copies have little or none. This test is not
infallible; some struck coins do not ring because of planchet defects such as
cracks or gas occlusions; also, some cast copies have been filled with glass (or
other substances) and do ring.
- A numismatic purchase that is bought substantially below the price for which it
can be resold.
- A set number of coins "rolled up" in a coin wrapper. In old times, a roll meant the
coins were rolled up in a paper wrapper, today they are likely to be slid into a
plastic coin tube. Groups of nineteenth century coins are sometimes referred to as
rolls when they exist in sufficient quantities even when they might not have come
in rolls during their years of issue nor or are they currently in a roll! (Cents are 50
to a roll, nickels 40 to a roll, dimes 50 to a roll, quarters 40 to a roll, half dollars
20 to a roll, and dollars 20 to a roll. Gold coins are sometimes seen in rolls but the
number of coins vary. Rolls of five dollar and twenty dollar coins have been
rolled 20, 40, and 50 to a roll -- other variations are certainly possible. Gold
dollars, quarter eagles, three-dollar coins, and eagles have also be seen in rolls of
- roll friction
- Minor displacement of metal, mainly on the high points, seen on coins stored in
- rolled edge
- Term synonymous with rim (the raised edge around a coin). This has become part
of the vernacular because of the Rolled Edge Indian Head eagle.
- Rolled Edge Ten
- Common name for the Indian Head eagle struck as a regular issue with a mintage
reported by some as 20,000, but according to official Mint correspondence the
figure was 31,550. However, some have considered it a pattern because all but 42
coins were reportedly melted. It is occasionally seen circulated but the average
coin is Mint State 63 or higher.
- roller marks
- Term to describe the mostly parallel incuse lines seen on some coins after
striking. These were originally thought to be lines resulting from debris "scoring"
the metal strips before the blanks were cut. However, new research has pointed to
the final step of strip preparation, the draw bar. To reduce the strips to proper
thickness, the final step was to pass them through the draw bar. It certainly seems
logical that debris in the draw bar may cause these lines, if so, then draw-bar
marks or lines would be a more appropriate term.
- Roman finish
- An experimental Proof surface used mainly on U.S. gold coins of 1909 and 1910.
This is a hybrid surface with more reflectivity than Matte surfaces but less than
brilliant Proofs. The surface is slightly scaly, similar to that of Satin Proofs.
- Short for a Pan-Pac commemorative fifty-dollar coin.
- Term for slight wear, often referring just to the high points or the fields.
- S VDB
- Short for 1909-S VDB Lincoln Head cent.
- Term applied to the coins struck at the San Francisco, California branch Mint.
- Short for Sacagawea Dollar.
- Sacagawea Dollar
- The Sacagawea dollar is a one dollar value circulating coin that was introduced in
the year 2000. It is also called the "golden dollar" in the non-numismatic
community because of its color. The coin honors Sacagawea, a Shoshone Indian
woman who was a guide and interpreter for the Lewis and Clark expedition of
1804. Glenna Goodacre designed the obverse of the coin and Thomas D. Rogers
created the reverse. Sacagawea dollars are struck for circulation at the
Philadelphia and Denver Mints, while Proofs are struck in San Francisco.
- Slang for the Saint-Gaudens inspired double eagle struck from 1907 until 1933.
(The 1933 issue is currently considered illegal to own as the government insists
that none of this date were legally released.) This low relief copy of the Extremely
High Relief and High Relief designs was the work of Chief Engraver Charles
- Last name of Augustus Saint-Gaudens, the preeminent sculptor of the late
nineteenth and early twentieth century. At the request of President Teddy
Roosevelt, he redesigned the eagle and double eagle in 1907 although he died
mid-production. Also, slang for the Liberty Head double eagle or Saint.
- saltwater Unc
- A very deceptive term. Generally, a term to describe coins with a finely pitted
surface, however, recent discoveries of coins that have been exposed to saltwater
for over a hundred years has made this term inaccurate, if not obsolete. The sand,
not the saltwater, likely does the pitting on gold and silver coins in the ocean. A
better term for these coins would be sandblasted Uncs or sand-damaged Uncs.
- San Francisco
- The United States branch Mint located in San Francisco, California that struck
coins from 1854 until 1955. After its closing as a Mint, it served as an assay office
until it reopened as a coinage facility in 1965.
- satin finish
- Another of the experimental Proof surfaces used on U.S. gold coins after 1907.
The dies were treated in some manner to create the silky surfaces imparted to the
- satin luster
- Fine, silky luster seen on many business strike coins, especially copper and nickel
issues. Almost no "cartwheel" effect is seen on coins with this type of luster.
- A detracting line that is more severe than a hairline.
The size of a coin determines the point at which a line ceases to
be viewed as a hairline and instead is regarded a scratch; the
larger the coin, the greater the tolerance. A heavy scratch may
result in a coin not being graded by PCGS.
- screw press
- The first
type of coining press used at the U.S. Mint. Invented by Italian
craftsman Donato Bramante, this press had a fixed anvil (or
lower) die, with the hammer (or upper) die being attached to a
rod with screw-like threads. When weighted arms attached to the
rod were rotated, the screw mechanism quickly moved the rod with
the die downward, striking the planchet placed into the lower
die. The struck coin then was ejected and the process was
- Short for small date.
- sea salvage coin
- A coin
retrieved from the ocean, usually from a ship wreck. The
conception that these coin will have pitted surface has been
exploded by the recent Brother Jonathon and Central America
recoveries. These coins do not have pitted surfaces! The action
of the shifting tides evidently causes sand to "blast" the
surface of some coins, while others protected from this action
retain nearly intact Mint luster.
- Short for Liberty Seated.
- Seated coinage
- Term commonly used for Liberty Seated
- second toning
- Any toning, natural or artificial, that
results after a coin is dipped or cleaned. This second toning is
seldom as attractive as original toning, although some coins
"take" second toning better than others.
- Term to denote coins that are neither scarce nor common. An example would
be Uncirculated 1903 Morgan dollars.
indicating a coin that has a significant bullion value and some
numismatic value. The most recognized examples are Liberty Head

- A term used to
describe a coin that has some mirror-like surface mixed with
satin or frosty luster. Reflectivity is obscured on such a
specimen, unlike the reflectivity on prooflike and deep mirror

period of time. This can used for a single denomination, or in
some cases, used for several denominations. The Liberty Seated
series encompasses five denominations, the Barber series three,
- A term indicating a collection of coins in a series, a
collection of types, or a collection from a particular Mint.
Examples include a complete series set (Lincoln cents from 1909
to date); a type set of gold coins (8 or 12 piece sets are the
most common); a set of branch mint quarter eagles (Dahlonega
quarter eagles from 1838 to 1859)
- Set Registry
- Listing of registered PCGS graded sets of coins. These include Morgan dollar
sets, Proof Barber quarter sets, Mercury dime sets, etc.
- Specifically, Dr. William Sheldon who wrote the seminal work on 1793 to 1814
- Sheldon Book
- The large cent book, first published in 1949 as Early American Cents with only
Dr. Sheldon listed, updated in 1958 with Walter Breen and Dorothy Paschal also
listed as authors with the new name, Penny Whimsy.
- Sheldon number
- The reference number for 1793 to 1814 large cents per the Sheldon books, Early
American Cents and Penny Whimsy. When certain Sheldon numbers are
mentioned among large cent aficionados, an immediate hush is observed until all
the facts of that particular specimen are disseminated.
- Sheldon scale
- The rarity scale introduced in 1949 in Early American Cents.
- The emblem used on certain issues that has horizontal and vertical lines in a
shield shape. These are first found in the center of the heraldic eagle and on each
succeeding eagle until the end of the Barber quarter series in 1916. They shield as
a single motif first appeared on the two-cent coins of 1864, later also used on the
nickels of 1866. Starting in 1860, Indian Head cents used the shield motif at the
top of the wreath on the reverse.
- Shield nickel
- Common name for the Shield five-cent coin struck from 1866 until 1883. The
1866 and some 1867 coins have rays between the stars on the reverse and are
referred to as Rays type (or With Rays type). Those 1867 through 1883 coins
without the rays are called No Rays type.
- shiny spots
- Areas on Matte, Roman, and Satin Proofs where the surface has been disturbed.
On brilliant Proofs, dull spots appear where there are disturbances; on textured-
surface coins such as Matte, Roman, and Satin Proofs, these disturbances create
- Shotgun rolls
- Rolls of coins that contain double the normal amount of coins in a roll. For
instance, a shotgun roll of silver dollars contains 40 coins. The name derives from
the length of the rolls being similar to the length of a shotgun barrel.
- Common term for a bourse or coin show. Example: the ANA show was great!
- sight seen
- A term to indicate that the buyer of a particular numismatic item in a particular
grade wants to view the coin before he buys it. He may have a customer who
wants an untoned coin -- or a toned coin, or some other specific requirement.
- sight unseen
- A term to indicate that the buyer of a particular numismatic item in a particular
grade will pay a certain price without examining the item.
- Term to indicate coins struck in silver (generally 90% silver and 10% copper but
there are a few exceptions).
- silver commem
- Short for silver commemorative coins.
- silver commemoratives
- Originally, those commemorative coins struck from 1892 until 1954, although not
in every year. These are all struck in 90% silver and 10% copper alloy. Of course,
those post-1982 silver commemorative issues also could technically be so called.
- silver dollar
- A coin of the one dollar denomination that is struck in a composition of 90%
silver (or so) and 10% copper. The silver dollar was introduced in 1794 and was
issued for circulation in intermittent years through 1935. The most frequently seen
silver dollars are the Morgan design (1878-1921) and the Peace design (1921-35).
These coins remained in circulation until the 1960s, mostly in the western US.
Modern dollar coins are sometimes called "silver dollars" as well, even though the
pieces struck for circulation contain no silver.
- Silver nickel
- Slang for Wartime nickel.
- Term to indicate a Kennedy half dollar struck from 1965 to 1970, whose overall
content is 40 percent silver and 60 percent copper. These are commonly referred
to as silver-clad halves because two outer layers containing primarily silver (80%)
are bonded to a core made primarily of copper (79%).
- skirt lines
- The lines representing the folds on Miss Liberty's flowing gown on Walking
Liberty half dollars. The early issues (1916-1918 and some coins through the
entire series) are particularly weak in this feature. Well struck coins with full skirt
lines often bring substantial premiums over those that are weakly struck.
- Short for small letters.
- Numismatic slang for the holder in which a coin is encapsulated by a grading
service. The coin contained therein is said to be slabbed.
- The process of sending a coin to a third-party grading service to have it
authenticated, graded, and encapsulated in a sonically sealed holder.
- A term used to describe an AU coin that looks, or can be sold as, Uncirculated.
Occasionally used as a reference to another grade; a slider EF coin, for example,
would be a VF/EF coin that is nearly EF.
- Slang for the octagonal and round fifty-dollar gold coins struck during the
California gold rush. Allegedly, their name came from the fact that criminals used
the two-and-one-half ounce coins wrapped in a handkerchief and slugged their
victims on the head with this "weapon." This could be a myth, as their massive
size also could be construed to be a "slug" of gold. The 1915 Pan-Pac fifty-dollar
commemorative issues are also referred to a slugs.
- small cent
- Those cents of reduced size, replacing the large cent in 1857. The 1856 small
cents technically are patterns, but have been so widely collected with the regular
issues that their acceptance is universal.
- small date
- Term referring to the size of the digits of the date on a coin. (Use of this term
implies that a large or medium date exists for that coin or series.)
- Small Eagle
- The plain eagle on a perch first used on the 1794 half dime and half dollar,
although the 1795 half eagle is the first coin to use the term to denote a type coin.
- small letters
- Term referring to the size of the lettering of the date on a coin. (Use of this term
implies that large or medium letters exist for that coin or series.)
- Small Motto
- Common short name for the particular variety of two-cent coin of 1864 with small
letters in the motto. The inscription "IN GOD WE TRUST" was first used as a
motto on the two-cent coinage of 1864.
See Also -- Large Motto

- Short for Specimen Strike.
- spark-erosion die
- A die made by an electrolytic deposition method. The surfaces of such a die are
very rough, so they usually are extensively polished to remove the "pimples." The
recessed areas of the die, and the relief areas of any coin struck with the die, still
have rustlike surfaces with tiny micro pimples.
- spark-erosion strike
- A coin made from spark-erosion dies. These are characterized by the telltale
"pimples" noted mainly on the areas in relief.
- Special Mint Set
- A set of special coins-neither business strikes nor Proofs-first struck in limited
quantities in 1965 and officially released in 1966-1967- to replace Proof sets,
which were discontinued as part of the U.S. Mint's efforts to stop coin hoarding.
The quality of many of the 1965 coins was not much better than that of business
strikes-but by 1967, some Special Mint Set (SMS) coins resembled Proofs. In
fact, the government admitted as much when it revealed how the 1967 issues were
struck. In 1968, Proof coinage resumed. There have been similar issues since; the
1994 and 1997 Matte-finish Jefferson nickels, for example, are frosted SMS-type
coins. There also are a few known 1964 SMS coins, these likely struck as tests in
late 1964 for the new 1965 SMS strikings.
- Term used to indicate special coins struck at the Mint from 1792-1816 that
display many characteristics of the later Proof coinage. Prior to 1817, the minting
equipment and technology was limited, so these coins do not have the "watery"
surfaces of later Proofs nor the evenness of strike of the close collar Proofs. PCGS
designates these coins SP.
- Specimen Strike
- See Also -- Specimen
- splotchy toning
- Color that is uneven, both in shade and composition.
- A discolored area on a coin. This can be a small dot of copper staining on a gold
coin or a large, dark "tar" spot on a copper coin. The spot(s) can have a small or
large effect on the grade of a coin depending on the severity, size, placement,
number, and so on.

- Common name of the Hermon MacNeil designed quarter dollar struck from 1917
- staple scratch
- A line on a coin resulting from its improper removal from a holder, usually one of
the two-by-two inch cardboard type. Staples should be completely removed from
any holder before the coin is removed!
- A term for the five-pointed and six-pointed devices used on many U.S. coins. On
the earliest U.S. coins, thirteen stars were depicted, representing the thirteen
original colonies/states. As new states were admitted into the Union, more stars
were added; up to sixteen appeared on some coins. Adding stars for each state
was impractical, however, so the number was reduced to the original thirteen.
Exception include the forty-six stars, later forty-eight stars, around the periphery
of Saint-Gaudens double eagles, reflecting the number of states in the Union at
the time those coins were issued. Also, as a single motif, the star was used on the
obverse of the three-cent silver issue from 1851 until 1873.
- State quarter
- One of the 1999 and later Washington quarters struck with unique reverse designs
for each state, issued in the order of admittance to the United States. (The order

- A term used to describe a coin that has been doctored in a specific way to cover
marks, hairlines, or other disturbances. Often associated with silver dollars, it
actually is used on many issues, mainly business strikes. The thumb is rubbed
lightly over the disturbances, and the oils in the skin help to disguise any
- tissue toning
- Color, often vibrant, acquired by coins stored in original Mint paper. Originally,
this was fairly heavy paper; later, very delicate tissue. Sometime during the
nineteenth century, the Mint began wrapping Proof coins, and occasionally
business strikes, in this paper. The paper contained sulfur; as a result, the coins
stored in it for long periods of time acquired blues, reds, yellows, and other
- A substitute for a coin. These have been issued in the past and are still currently
issued in huge quantities. Older ones generally were issued by stores and may not

"fix" the problem.
- Trade dollar
- A U.S. silver coin, issued from 1873 until 1885, slightly heavier than the regular

- A collectibles rarity information scale developed in 1998 by 21 major collectibles
experts in order to both define rarity within their individual markets and allow
collectors and dealers from different collectibles markets to more easily
communicate with one another. The Universal Rarity Scale is a 10 point scale.
The least rare collectible items are those where more than 10,000 examples are
estimated to exist. These items are designated "UR1" and are described as
"readily available." The rarest items are those where only one example is known
to exist. These rarities are designated "UR10" and are described as "unique."
- Short for Universal Rarity Scale.
- term to describe a coin that has light to heavy wear or circulation.
- Common name for the Liberty Head five-cent coins struck from 1883 through
1912. (The 1913 was struck clandestinely and is not listed in Mint reports.)
- VAM number
- Unique number assigned to each die combination of Morgan and Peace dollar
known to the authors of The Complete Catalog and Encyclopedia of United States
Morgan and Peace Silver Dollars. Called VAM because of the authors Leroy Van
Allen and A. George Mallis.
- Van Allen-Mallis
- The Morgan and Peace dollar variety book authors. First published in 1971, it was
updated and reprinted in 1998.
- A coin of the same date and basic design as another but with slight differences.
PCGS recognizes all major varieties while there are thousands of minor varieties,
most of which have significance only to specialists of the particular series. After
hubbed dies, introduced in the 1840s, varieties are mainly variations in date and
mintmark size and placement.
- Short for 1909 VDB Lincoln Head cent. Controversy arose over having a non-
Mint engraver's initials on a coin, so Victor D. Brenner's initials were removed.
This was likely a jealous complaint from the Chief Engraver Charles Barber as
the tiny B on the Barber series had generated no outcry. This is a similar situation
to the complaint lodged, again probably by the Chief Engraver of the time
William Kneass, against the name-below-base Gobrecht dollars. This overt
signing was moved to a less obvious position on the base of the rock of the
Gobrecht dollar while, in 1918, the VDB was returned to the Lincoln Head cent
albeit in a less conspicuous place on the slanted area at the bottom of Lincoln's
- The grader at PCGS who looks at graded coins and decides whether the indicated
grade is correct. He may tag a coin to be looked at again by the graders.
- Very Fine
- The term corresponding to the grades VF-20, 25, 30, and 35. This has the broadest
range of any circulated grade, with nearly full detail on some VF-35 coins and
less than half on some VF-20 specimens.
- Very Good
- The term corresponding to the grades VG-8 and VG-10. In these grades, between
Good and Fine, a coin has slightly more detail than in Good, usually with full
rims except on certain series such as Buffalo nickels.
- vest pocket dealer
- A part-time coin merchant. The term originated with those individuals who
roamed the bourse floor ready to whip out of their vests a small plastic coin
binder containing coins in two-by-two cardboard holders. Today, not one-in-a-
thousand individuals wears a vest, but the moniker stuck.
- This is for "Very Fine" (the grade) and "20" (the numerical designation of the
grade). Wing feathers show most of their detail, lettering is readable but
sometimes indistinct and some minor detail is sometimes separate but usually
- This is for "Very Fine" (the grade) and "25" (the numerical designation of the
grade). In this grade about 60% of the original detail is evident, with the major
devices being clear and distinct.
- This is for "Very Fine" (the grade) and "30" (the numerical designation of the
grade). The devices are sharp with only a small amount of blending. Up to 75% of
the original detail is evident.
- This is for "Very Fine" (the grade) and "35" (the numerical designation of the
grade). This grade used to be called VF/EF (or VF/XF) before numerical grading
was accepted throughout the hobby. Devices are sharp and clear and up to 80% of
the detail is in evidence.
- This is for "Very Good" (the grade) and "10" (the numerical designation of the
grade). A higher grade (less worn) than the VG-8 coin. Design detail is still
heavily worn but the major devices and lettering are clear.
- This is for "Very Good" (the grade) and "8" (the numerical designation of the
grade). A slight amount of design detail is still showing on the coin, such as a
couple of letters in the word LIBERTY.
- Slang for a Walking Liberty half dollar.
- Walking Liberty
- Common name for a Walking Liberty half dollar.
- Walking Liberty half dollar
- Those half dollars struck from 1916 until 1947. The Walking Liberty design by
A.A. Weinman undoubtedly was inspired by the popular Saint-Gaudens/Charles
Barber Liberty Standing double eagle then current.
- War nickel
- Short for Wartime nickel.
- Wartime nickel
- Those five-cent coins struck during World War II comprised of 35% silver, 9%
manganese, and 56% copper. Tradition has been that nickel was needed for the
war effort, hence the metallic change. However, recent research has shown that
the boost to morale by having an intrinsic-value small denomination coin may
have played an important part in the issuance of the Wartime nickel.
- Washington quarter
- Short for Washington quarter dollar.
- Washington quarter dollar
- The John Flanagan designed quarter dollar first struck in 1932 as a circulating
commemorative coin. (This was to celebrate the two-hundredth anniversary of
George Washington's birth.) It became a continuing series in 1934 and has been
struck every year to 1998, albeit with a different reverse in 1976. In 1999, the
obverse was redesigned and the State quarter series began to be struck. Each of
the 50 State quarters will have a different reverse design with 5 new issues per
year for 10 years.
- watery look
- A look seen on the surfaces of most close-collar Proof coins. Highly polished
planchets and dies give the surfaces an almost "wavy" look-hence the term.
- weak strike
- A term used to describe a coin that does not show intended detail because of
improper striking pressure or improperly aligned dies.
- An individual who is obsessed with a particular series or group of series.
Examples are copper weenies, bust half weenies, etc.
- wheel mark

- Term to describe the process of mechanically moving the metal of a lightly
circulated coin to simulate luster. Usually accomplished by using a wire brush
attachment on a high-speed drill.
- wire edge
- The thin, knife-like projection seen on some rims created when metal flows
between the collar and the dies. Also, slang for the Wire Edge Indian Head eagle
See Also -- knife edge wire rim
- Wire Edge eagle
- The 1907 Indian Head eagle for which only 500 coins were struck. Technically, a
pattern, this design featured a fine wire rim and surfaces unlike any other United
States issue. The fields and the devices of the die were heavily polished leaving
myriad die striations that transferred to the struck coins. With a combination of
satiny and striated surfaces, these rare coins have a look of their own. Often,
unknowledgeable numismatists will look at one of these specimens and declare it
hairlined or harshly cleaned.
- Wire Edge Ten
- Common name for the 1907-dated Wire Edge Indian Head eagle.
- wire rim
- Alternate form of wire edge.

required for coinage.
- World Coins
- Term applied to coins from countries other than the United States.
- worn die
- A die that has lost detail from extended use. Dies were often used until they wore
out or were excessively cracked or broke apart. Coins struck from worn dies often
appear to be weakly struck but no amount of striking pressure will produce detail
that does not exist.
- Wreath cent
- Common name for the second large cent type of 1793. Complaints about the
Chain cent led to the redesign resulting in the Flowing Hair with wreath reverse
- Short for EF-40
- Short for EF-45
- Zerbe Proof
- Those 1921 Morgan dollars specially struck for numismatist and Mint friend
Farran Zerbe. These Proofs are not of the same quality as the other Proof Morgan
dollars. The devices on these specimens usually are not frosted while the fields
lack the depth of mirror normally associated with Proofs. In fact, the fields are
characterized by heavy die polish, the planchets likely not burnished before
striking. (Both Philadelphia and San Francisco examples are known.)
