Cam,Dcam question.

smprfi

71 Proof set.

Does there have to be frosting on the coin to get dcam like on the nickel or is it something else?
I stand a $20 bill up and can see the 20 at the far end of the bill in the fields of these coins.
Is the frosting the difference between cameo and deep cameo?

It's the "black+white" contrast. It's not like dmpl.

From the pcgs coin lingo.

Deep Cameo
The term applied to coins, usually Proofs and prooflike coins, that have deeply frosted devices and lettering that contrast with the fields - often called “black and white” cameos. Specifically applied to those 1950 and later Proofs that meet deep cameo standards (DCAM).


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).
