Much scarcer than regular proof set...
Since 1992, the U.S. Mint has issued special silver proof sets reviving the tradition of 90% silver dimes, quarters and half dollars. This 1992 first set in the series had a mintage of 1,009,586, far below the regular proof set’s 2.6 million. Struck by the San Francisco Mint with finest-quality, double-struck engravings, it features beautiful frosted finishes against dazzling mirror backgrounds. Included are superlative cent, nickel, dime, quarter and half dollar proofs.
