Glossary


Numismatics, like any specialized field, has a language of its own. This glossary is a comprehensive list of terms and slang that you may encounter in your collecting pursuits. This list was compiled using several extraordinary reference works and the experience of our numismatists. 

A

Adjustment Marks
File marks made by the mint on a silver or gold planchet to correct its weight.
 
Alloy
A mixture of two or more metals, e.g. the Sacagawea Dollar is comprised of an alloy of .770 copper, .120 zinc, .070 manganese, and .040 nickel.
 
Altered Surfaces
A designation given to coins which cannot be certified with a numeric grade due to any number of alterations to its surfaces after it left the mint. Such adjustments or alterations include CLEANING, lacquering, PUTTYING, TOOLING and ARTIFICIAL TONING. See also: BODY BAG.
 
Anvil Die
The DIE upon which a PLANCHET rests prior to striking.
 
ANA / American Numismatic Association
The main hobby organization and host of the industry's largest coin show each year. Individual membership cost is approximately $28 / year. Lot's of benefits to membership. For more information, contact them at http://www.money.org/ or call 1-800-367-9723.
 
Annealing
The process of softening BLANKS and PLANCHETS, through heat, which enables the metal to flow more freely into the cavities of the DIE or HUB when struck. If the temperature and length of exposure to the heat are not correct in the annealing process, the design could be improperly struck up.

Ask
Usually refers to the wholesale asking price of a certain coin as published in The Coin Dealer Newsletter or other price directory (e.g. What's the GREYSHEET "ask" on this 1941-S Walking Half?).

Assay
A test undertaken to find the metallic content of a coin, INGOT or ORE sample.

Assay Office
An establishment or department of government that assures the content and quality of a coins ALLOY.

Assay Piece
A coin selected to be ASSAYED, or produced for an ASSAYER.

AT / Artificial Toning
Patina applied to the surface of a coin, either by chemical or physical means, for the purpose of hiding hairlines and other flaws or to resemble the natural oxidation process that can increas a coin's desirability. See also TONING.

AU / About Uncirculated
Just as the term suggests, it refers to a coin's condition - specifically, a coin which shows only very slight signs of wear or damage. In relation to the SHELDON scale, the AU designation corresponds to the numerical grades between 50-58.

Authentic
As represented. Genuine. Made when and where the coin purports to have been made.

 

B

Bag Mark(s)
This term refers to the hits and ticks on coins which were caused by contact with other coins. During the early years of MINTING, coins were ejected from the presses and into bins or bags along with numerous other coins. The bags were usually thrown around creating lots of "bag-marks". Coins with the fewest bag-marks are obviously more valuable as one of the primary criteria in GRADING concerns the number of hits, ticks and bag-marks. See also: HITS, CHATTER.
 
Bands
See FULL-BANDS.
 
Barber, Charles (1840-1917)
Succeeded his father, William Barber as Chief Engraver of the US Mint in Philadelphia in 1879. During his tenure, he is credited with designing many MEDALS, plaques and PATTERN coinage but is best remembered for his 1879 Flowing Hair $4 STELLA, 1883 Liberty nickel and the dime, quarter and half-dollars issued between 1892-1916. He was succeeded by GEORGE T. MORGAN.

A metal not classified as a PRECIOUS METAL (i.e. copper, zinc).
 
Basining
The process of polishing the surfaces of a DIE. The process consists of placing the die against a rotating zinc dish. The process was used so that coins would STRIKE-up properly. Newly polished dies were a major factor in the production of PROOFLIKE dollars.

Bid
Usually refers to the published wholesale value of a certain coin as published in the Coin Dealer Newsletter or other numismatic price directory (e.g. What's the GREYSHEET "bid" for a 1916-D MERC dime?). Otherwise, it could simply refer to a dealers offer to buy a certain coin (e.g. I would bid $2,200 for your proof BARBER quarter). Also used as an auction term; "I placed a bid on the Alabama commemorative in last night's auction.

Billon
An ALLOY of gold or silver with a predominant base metal, e.g. 75% copper and 25% silver. Usually applies to mixture of silver and copper in which copper predominates.

Bit
Any coin valued at 1/8 dollar. A 25c piece is sometimes referred to as "two bits".

Blank
A disc of metal intended to become a coin. A "blank" is not a PLANCHET until it goes through the UPSETTING MILL which creates the raised rims. "Blanking" is done by shearing blanks from metal strips - much like a cookie cutter.

Bloom

The term used to refer to the lustrous appearance of a coin immediately after striking - caused by the clash of the metal DIE and PLANCHET.

Carbon Spot
A black discoloration on a coin which was on a PLANCHET prior to the ANNEALING process. The discoloration may have been caused by burnt wood or sawdust, charcoal particles or sulfides. Even the high temperature of the annealing furnaces often cannot rid the planchet of these particles. The term can also designate black carbonate spots created by minute droplets of saliva.

Chop Marks
Found primarily on American Trade dollars dated 1873-1878 and Japanese Yen dated 1870-1914 which were circulated throughout the Orient. Chinese businessmen, ever watchful for fakes, placed their sign or "chop" on any of these trade coins that passed muster. Numerous pieces are found with multiple chop marks on both sides.

Cinci

Classic Rarity
There have always been certain "special" issues which over time, have proven themselves to be the most popular coins to the numismatic community. The issue date doesn't necessarily have to be the single most rare date in a series but is almost certainly scarce. For example, the 1909-S VDB Lincoln cent or the 1934-S Peace dollar. See also: STOPPER, KEY DATE

Commem
Short for Commemorative Coin

Commodity
In relation to NUMISMATICS, this term is used to describe how dealers buy and sell the most common issues. The founders of PCGS and NGC envisioned creating a standard of GRADING which would be so accepted by the rare coin industry that certified coins could be traded SIGHT-UNSEEN much like a traditional "commodity" (i.e. gold, pork-bellies, etc.) is traded on an electronic exchange. See also: CCE

Common (Date)
Refers to the most populous issues in a series. For example, the 1881-S in MS65 is the most "common date" in the Morgan dollar series.

D

Debased
Refers to underweight coins or coins whose precious metal content is inferior to legal standards (or to those claimed on a coin's face). "Debased" coins are not necessarily COUNTERFEIT.

Face value of a coin.
 
Devices
Refers to the raised relief and lettering on a coin such as the bust of Ms. Liberty on $20 gold pieces or the eagle on the reverse of a Walking Liberty half-dollar. The devices are a critical focal point when grading a rare coin. A coin's GRADE is determined in no small part to how well-struck these devices are. In addition, it is often the devices which show the first signs of WEAR - another important consideration when determining the grade. See also: STRIKED ie An INCUSE (depressed) design on the end of a short steel rod used to strike PLANCHETS to make coins. Prior to 1996, all dies were made at the Philadelphia mint

Die Breaks
Raised irregular areas on a coin, the result of metal from the planchet being forced through a portion of the DIE which has broken and fallen out during the minting process.

Die Cracks

The friction of the plastic against the coin's DEVICES sometimes caused un-removable lines to appear.

Slider
A slang term referring to a coin that objectively may only grade AU or even XF - but gets marketed as an UNCIRCULATED piece (particularly when the coin is CLEANED). The term is usually used in a negative sense as unscrupulous dealers will often overgrade their coins in order to reap a higher price.
