1938 Lincoln Cent. Proof-67 RD Cameo (PCGS). CAC. This awe-inspiring Superb Gem possesses an uncommon degree of field to device contrast for an issue that was produced as a Brilliant Proof. Field to device contrast is more pronounced on the obverse, where Lincolns portrait is lightly frosted and contrasts markedly with deep mirrored reflectivity in the surrounding field. A cameo finish is also evident on the reverse, nonetheless, and both sides of further enhanced by gorgeous mint color in vivid deep orange and pinkish-rose. Virtually pristine, as well, this coin belongs in the finest Proof Lincoln cent collection on the PCGS Set Registry. From a mintage of 14,734 Proofs for the date, the typical survivor of which is universally brilliant in finish and will not qualify for a coveted CAM designation from the major third party certification services.
