About Good - The grade AG-3. The grade for a coin that is just below good. On an About Good coin, only its main features are present. The date, mintmark, peripheral lettering, or other features are sometimes partially worn away.
About Uncirculated - The grades AU50, 53, 55, and 58. A coin with an AU grade initially appears to be in mint state condition. Upon further inspection it is found to have slight friction or rub keeping it from a mint state grade. Same as Almost Uncirculated.
Abrasions - An abrasion is an area of a coin where
another coin or a foreign object has displaced metal in an
abraded fashion.
Accolated - Design with two heads facing the same
direction and overlapping. An example of this type of coin
is the 1900 Lafayette Dollar.
Accumulation - Quantities of coins that have not been
sorted, classified, attributed or organized in any
meaningful way. A true coin collection is organized and
generally follows a pattern or series.
Adjustment Marks - File marks made by the U.S. Mint on silver or gold coin blanks to correct the metal content and make them the perfect weight.
Aes grave - Cast bronze coins of the Roman republic; literal translation is "heavy bronze".
Aes rude - Large cast rectangular bronze coin, one of the earliest Roman coins. These coins circulated well before 500 BC and were exchanged by weight.
AG - Acronym for About Good.
AG-3 - Acronym for About Good. (the grade) and "3"
(numerical designation). Most of the lettering on the coin
is readable, but there is moderately heavy wear into the
rims.
AGW - Actual Gold Weight - This refers to the amount of pure gold in a coin, medal or bar. Any alloys are part of the gross weight of a gold coin, but not part of the AGW.
Album - A holder with slots for storing and displaying coins in a book. Common brand names include Whitman and Dansco.
Album friction - A less severe instance of album
slide marks. Album friction shows as slight rubbing on the
high points.
Album slide marks - Lines that are imparted to the
surface of a coin by the plastic “slide” of an album, mostly
found on proof coins in the form of hairline scratches.
Alloy - A combination of two or more metals.
Almost Uncirculated - The grades AU50, 53, 55, and
58. A coin with an AU grade initially appears to be in mint
state condition. Upon further inspection it is found to have
slight friction or rub keeping it from a mint state grade.
Same as About Uncirculated.
Altered - A coin, banknote, or other numismatic item that has been deliberately changed. The alteration is usually done to make it resemble a rare or more valuable piece.

nonprofit organization, that is the largest and most active
numismatic body in the world. It invites and welcomes to
membership all persons who have a sincere interest in
numismatics, whether they collect coins, paper money, tokens
or medals, whether advanced collectors or those only
generally interested in the subject.
ANACS American Numismatic Association Certification

later provided grading services. The grading service and
acronym were sold by the ANA and now operate under this name
as a third-party grading service.
ANACS Certificate - A uniquely numbered opinion of

Anglo American Coins & Tokens - The term Anglo
American is applied to issues that were struck in Britain in
the 17th and 18th centuries for use in the American
colonies. These coins and tokens were intended primarily or
exclusively for British circulation but found their way to
this country.
Annealing - The process of heating up coin planchets,
just prior to striking in order to make them soft and thus
receive a better impression of the design.
Annular - Ring-shaped. Many world coins, mostly in low denominations, and even some US coin patterns are annular.
ANS - Acronym for "American Numismatic Society".
Ant nose - Primitive copper money of China minted around 600 B.C.
Anvil die - The anvil die is the lower stationary die. This die is usually the reverse of the coin, although on some issues with striking problems, the obverse was employed as the lower die. Due to the physics of minting, the fixed lower-die impression is slightly better struck than the upper-die impression.
Arrows - Design element usually found in the left
(viewer’s right) claw of the eagle seen on many US coins.
Arrows and rays - Term referring to 1853 quarters and
half dollars. In 1854 the rays were removed due to striking
difficulties created by the busy design.
Arrows at date - Term referring to the arrows to the
left and right of the date. Arrows were added to the dies to
indicate a weight increase or decrease.
Artificial toning - Adding color's to a coin by
various treatments with chemicals, heat and other methods in
an attempt to increase its value. Coins with natural toning
may at times provide exceptional eye-appeal and command
higher prices than an untoned specimens A coin that is known
to have been artificially toned (a deceptive practice) will
bring much lower than usual prices.
As - Bronze or orichalcum coins of the Roman republic.

AU - Acronym for About Uncirculated.
AU-50 - Acronym for About Uncirculated (the grade) and "50" (numerical designation). 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.
AU-53 - Acronym for About Uncirculated (the grade) and "53" (numerical designation). 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.
AU-55 - Acronym for About Uncirculated (the grade) and "55" (numerical designation). 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.
AU-58 - Acronym for About Uncirculated (the grade) and "58" (numerical designation). 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.
