Cameo

The term applied to coins, usually Proofs and prooflike coins, that have frosted devices and lettering that contrast with the fields. When this is deep the coins are said to be "black and white" cameos. Occasionally frosty coins have "cameo" devices though they obviously do not contrast as dramatically with the fields as the cameo devices of Proofs do. Specifically applied by PCGS to those 1950 and later Proofs that meet cameo standards (CAM).
