Today, this Mint manufactures coins of all denominations for general circulation, medals, coin dies, stores gold and silver bullion, manufactures uncirculated coin sets and commemorative coins. This mint uses the “D” mintmark.

Design

A particular motif on a coin or other numismatic item. The Seated Liberty, Barber, Morgan, etc. are examples of designs.

Designer

The individual responsible for a particular motif used for a numismatic series.

Device

Any specific design element. Often refers to the principal design element.

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.

Die

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 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. Dies are made of steel and they crack from use and have to be checked often. When the die 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

Raised, irregular lines on a coin, the result of a die having cracked and metal being forced through those cracks at the time of striking

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 Polish(ing)

An area of raised lines or highly reflective area of a coin, most often in the fields, that resulted from striking from dies that had been recently polished.

Die Rust

Rust that has accumulated on a die that was not stored properly.

Die Stage

There are two definitions for this term. One, many numismatists use it as a synonym for "die state." Two, some numismatists use the term "die stage" to refer to the specific status of a certain die state.

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.

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.

Dime

The denomination, one tenth of a dollar, issued since 1796 by the United States.

Ding

Jargon term for a small to medium size mark.

Dipped

A term applied to a coin that has been placed in a commercial cleaning liquid, it can be 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. Dipping coins will remove tarnish, natural toning or dirt from a coin.

Dipping Solution

Any of the commercial "dips" available on the market, usually acid-based.

Double Edge Lettering-Overlap
