A Back to Top
About Good	The grade AG-3. The grade for a coin that is just below good. On an About Good coin, only the main features of it are present. Date, mintmark, peripheral lettering, or other features sometimes are partially worn away.
About Uncirculated	Alternate term for Almost Uncirculated.
Abrasions	Areas of a coin where another coin or a foreign object has displaced metal in an abraded fashion.
Accumulation	A grouping of a particular date, type, or series. Example: an accumulation of Morgan Dollars. A random grouping of coins, often as a monetary hoard. Opposite of a coin collection.
Adjustment marks	Scratches which appear mostly on pre-1807 silver and gold coinage. These scratches are actually file marks, made at the mint in order to reduce the weight of a coin so that its metal value wouldn't exceed its face value. As a rule, adjustment marks do not reduce the value of a coin nearly as much as a series of equally visible scratches, which were not "mint-applied".
AG	Acronym for About Good.
Album friction	A less severe instance of album slide marks. Album friction shows as slight rubbing on the high points.
Album slide marks	Lines (often parallel) imparted to the surface of a coin by the plastic "slide" of an album, mostly found on proof coins.
Alloy	A combination of two or more metals.
Almost Uncirculated	The grades AU50, 53, 55, and 58. These coins often look Uncirculated at first glance, but closer inspection will reveal slight friction or rub.

Anvil die	The lower, stationary die. The reverse is usually the anvil die, 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. Also see: Hammer die
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. The rays were removed in 1854 because of striking difficulties created by the busy design.

Bag	A generic term for the cloth sacks used to transport and store coins. These came into use in the mid-nineteenth century and replaced wooden kegs. Also refers to the quantity of coins of a particular denomination found in a bag (such as 5000 cents or 1000 silver dollars).
Bag marks	Abrasions which occur on coins that were shipped in mint bags. Most often this term applies to silver dollars, although virtually any coin can have bag marks. Bag marks in no way mean that a coin is not mint state. In fact, even a coin graded Mint State-67 or higher could have some bag marks.
Bag toning	Coloring acquired from the bag while a coin was stored. Cloth coin bags contained sulfur and other metal-reactive chemicals. When stored in bags for extended periods, coins in close proximity to the cloth often acquire beautiful red, yellow, blue and other vibrant colors. Sometimes the weave of the cloth is visible in the toning. Some coins have crescent-shaped toning because another coin was covering part of the surface, thus preventing toning. Bag toning is seen most often on Morgan silver dollars.
Barber coinage	Common name for the Charles Barber designed Liberty Head dimes, quarters, and half dollars struck during the 1890s and early 1900s.

The procedure was done originally by rubbing wet sand across the surfaces to impart a mirror-like finish. In a negative sense, the surfaces on repaired or altered coins may be burnished by mechanical or chemical methods. For example, a high-speed drill with a wire brush attachment is used to achieve this effect.
Burnishing lines	Lines resulting from burnishing. Typically seen on open-collar Proofs and almost never observed on close-collar Proofs.
Burnt	Slang term for a coin that has been over-dipped. On such a coin, the surfaces are dull and lackluster.

Capped die	An error in which a coin gets jammed in the coining press and remains for successive strikes. Eventually a "cap" is formed on either the upper or lower die. These are sometimes spectacular, with the cap often many times taller than a normal coin.
Carbon spot	A dark discoloration on the surface of a coin. It is possible that this discoloration is caused by a planchet imperfection prior to striking, or it may be caused by improper storage of the coin. Regardless of the cause, carbon spots are often difficult, if not impossible, to remove without leaving pits in the coin's surface. If they are large enough, they may significantly lower the grade and value of a coin. Also, see Copper spot.
Carson City	The United States branch Mint located in Carson City, Nevada that struck coins from 1870 through 1885 and later from 1889 through 1893. More information on mintmarks.

Cleaning Coins	DO NOT CLEAN YOUR COINS! Just like any antique piece of furniture, or painting, the original surfaces of a coin are much more desirable by collectors than altered or damaged surfaces. As a result, cleaned coins are worth significantly less money than wholly original coins. Even though a coin is dark in color, does not mean that it is less valuable. The metal in coins often oxidizes and produces a wide array of colors called toning. Some collectors hunt for wholly original coins with this type of toning.

Conserved	Numismatic conservation involves examination, scientific analysis, and a reliance upon an extensive base of numismatic knowledge to determine the nature of a coin's state of preservation and the extent of any damage. Conservation also encompasses appropriate procedures to protect the coin's original appearance and to guard against future deterioration to whatever extent possible. Professional conservation should not be confused with "Coin Doctoring", in which an attempt is made to improve the appearance and grade of a coin through deceptive means such as artificial toning and where unaccepted or unorthodox methods are employed. Also not qualifying as conservation is restoration where mechanical repairs are made such as filling holes, smoothing out scratches, and re-engraving of detail.
Contact marks	Marks on a coin that are caused by contact with another coin or a foreign object. These are generally small, compared to other types of marks such as gouges. Also, see Bag mark.
Contemporary counterfeit	A coin, usually base metal, struck from crude dies and made to pass for legal tender at the time of creation. Sometimes such counterfeits are collected along with the genuine coins, particularly in the case of American Colonial issues.
Continental dollars	"Dollars" struck in pewter (scarce), brass (rare), copper (extremely rare) and silver (extremely rare) that are dated 1776, but likely struck sometime later. Certain Benjamin Franklin sketches inspired the design.

If shifting occurs in the alignment between a hub and a die, the die will have some of its features doubled. This doubling is then imparted to every coin it strikes. The coins struck from such dies are called doubled-die errors. The 1955 Doubled Die Lincoln cent is one such error.
Double-struck	A condition that results when a coin is not ejected from a die and is struck a second time (hence double-struck). Triple-struck coins and other multiple strikings also are known. Proofs are usually intentionally double-struck in order to sharpen their details; this is sometimes visible under magnification.
Draped Bust	The design of Miss Liberty with a drape across her bust. This is attributed to Mint engraver Robert Scot, who presumably copied the design after a portrait by Gilbert Stuart.
Drift mark	An area on a coin, often rather long, that appears streaky or discolored. This is the result of impurities or foreign matter in the dies.

Heritage Value Index™	The Heritage Value Index™ is based on recent wholesale and auction transactions for NGC and PCGS certified coins. Infrequently traded coins may therefore show outdated prices. Our experts constantly refine and adjust individual prices based on their trading experience, but errors are still possible. If you notice any mistakes in the prices listed, or can suggest adjustments based upon more recent sales records, please e-mail your comments to JimS@HA.com so we can adjust these prices accordingly. These value ranges should not be considered an offer to buy or sell. Many factors go into pricing coins including relative rarity and eye appeal. The listed prices do not apply to coins graded by services other than NGC and PCGS, and even some NGC and PCGS coins may sell for substantially under or over these price ranges. Please use them as an indication only.
