Damaged Coin

A coin that has been impaired apart from normal wear, by scraping, drilling, polishing, or other abuse. Generally, a damaged coin will not be given a stand-alone grading designation but will be described adjectivally. Example: 1822 cent, holed at the top, otherwise VF-30. Such a coin must not be simply described as VF-30 without further comment.

Deep Cameo Contrast

Describes the portrait or devices on a Proof coin being especially frosted or satiny, or cameo, in contrast with mirrorlike fields. Abbreviated DCAM. Seemingly more contrasted than Cameo (CAM). Certain of this is semantics, with actual differences being slight between various cameo designations.

Deep Mirror Prooflike

Designation

A characteristic added to a coin's grade that specifies a certain attribute or quality such as color, strike or appearance not covered by the numerical grade. Not all series and denominations have designations, but for those that do, the associated designation will affect the coin's value. Copper coins have color designations of Red, Red-Brown, and Brown. Standing Liberty quarters can have the designation of Full Head, where Miss Liberty's head is fully struck. Some other designations include: Prooflike, Deep Cameo, Deep Mirror Prooflike.

Designer

Details

Small features and fine lines in a coin design, particularly those seen in hair, leaves, wreaths, and feathers.

Die Alignment

A term that indicates that the obverse and reverse dies are in their proper position and will strike a coin evenly.

Die Break

A raised area on a coin caused by metal filling the space caused from a small chip or piece falling out of a die. Those at the rim of a coin are called cuds or cud breaks. Die breaks can be interesting and have no effect on grade or market value of older coins but for a modern issue can command a great premium.

Die Crack

A raised ridge, often irregular, on the surface of a coin, caused by a crack in the die, and metal from the planchet filling the crack. Die cracks can be interesting and have no effect on grade or market value of older coins but for a modern issue can command a great premium.

Die Line

Appearing as raised lines on a coin, these are caused by polish lines on the die.

Die Polish

Refers to a “bright” or mirrorlike spot or area, not the entire surface, of a coin, where a working die was polished slightly to remove an imperfection, rust, etc. Heavy die polishing is a different matter, and refers to the entire field of a coin being resurfaced, also called relapping. Heavy die polishing sometimes resulted in the removal of low-relief details in a coin, while at the same time giving a prooflike surface.

Die Rust

Raised grainy patches on a coin caused by rust on the die, often the result of improper storage.

Die State

An easily identified point in the life span of a coinage die. Dies can clash, rust, crack, break, etc., and evidence of such represents a different state of the die. Certain coins have barely distinguishable die states, while others show multiple distinctive die states.

Raised lines on coins caused by having been struck with polished dies, similar to die lines.

Die Trial

Disme

Doubloon

Spanish-American 8-escudos gold coin equal to about $16 U.S. Such coins were legal tender in the United States until the implementation of the Act of February 21, 1857, but were mainly used in large commercial transactions, not in everyday change.
