1872 Liberty Seated Silver Dollar. Proof-65+ Deep Cameo (PCGS). CAC. This awe-inspiring Gem really needs to be seen to be fully appreciated. Ice-white surfaces are fully untoned and devoid of even the lightest iridescent toning. Also absent are grade-limiting marks, and conspicuously so for a large size silver coin with delicate Proof surfaces. Razor sharp in detail, the frosty design elements contrast starkly with deeply mirrored fields to deliver awesome cameo contrast. From a mintage of 950 Proofs, many of which may have been melted in the Mint after the Act of February 12, 1873, abolished the standard silver dollar. Dick Osburn and Brian Cushing estimate that 575 Proofs remain, although with the typical survivor grading no finer than Proof-64, and rarely with a DCAM designation, the significance of this upper end specimen is beyond contestation. PCGS# 97020. NGC ID: 252U. PCGS Population: 1; 0 finer in this category.CAC Population: 2; 0. The former total includes coins certified both Proof-65 Deep Cameo and Proof-65+ Deep Cameo.
