1971 & 1983 U.S. Proof Sets |
|
|
Proof sets had been briefly discontinued after the last Philadelphia issue of 1964. But since 1968 exclusive San Francisco Mint U.S. proof sets have come to be regarded as the finest in American minting history. The 1971 U.S. proof set, with a mintage of 3.2 million, was one of the first S-mint proof set issues. It contains finest-quality proofs of the 1971 cent, nickel, dime, quarter and half dollar (the 1971 Ike dollar proof was issued separately). The 1983 proof set’s mintage of 3.1 million was the series’ lowest in several years. But today it’s among the most affordable of U.S. proof sets. Each set contains five proof coins with double-struck, deep-sculpted engravings and mirror fields.
