Record 4 1997-01-29

English

Subject field(s)
  • Coins and Bank Notes
  • Numismatics
  • Coining
OBS

An unofficial numismatic term used to describe the reflective fields of proofs and prooflikes. Mirror depth can be measured by holding printed matter in front of a coin and increasing the distance between the two. If the printing is reflected in the field but is not clear at a distance of under one inch, the coin is semi-prooflike; if clearly reflected, that is readable, at a distance of one to four inches, the coin is prooflike and has a deep mirror; similarly at four to eight inches, it is very deep, and ultra deep beyond eight inches.

OBS

See related term: cameo contrast.

DEF

The fields of a cameo coin can range from "black" (deep mirror) to silver-appearing (semi-prooflike). The degree of contrast can be subdivided into degrees as "slight", "excellent", and "outstanding". An outstanding contrast is also known as "black and white".
