Proof coins with highly reflective, mirror-like fields can be described as either cameo (abbreviated to “CAM” on the PCGS certificate) or deep. The cameo effect on a proof coin is produced by the field having a mirror-like surface and the coin's devices having a frosted surface. Over the years, proof coins struck at the U.S. Mint have had different finishes, such as a Roman finish, Satin finish, Matte finish, Reverse Proof.

A proof copper coin with full red in grade, say, 63 that has frosting on only one side of the coin but deeply reflective fields on both sides of the coin is described as PR63RD CAM. As a result, historically, only a small number of proof coins were originally produced.
