Proof Lincoln Cents
1990 1C No S, FS-101, PR67 Red Deep Cameo PCGS. The 1990 No S is the key to the proof Memorial Reverse series. It is especially rare in high grades, since many examples exhibit green rim verdigris from longtime storage in unduly humid Mint holders. But the present Superb Gem has pristine rims in addition to a needle-sharp strike and blatant cameo contrast. The textured fields are flawless.
