An incredible 41 years of US mint history is yours all at one time! This set includes every United States regular-issue proof set from 1960 - 1964 and 1968 - 2000. You also receive the 1965 - 1967 Special Mint Sets, representative of the years in which no proof sets were made because the government was moving their proof-making area from the Philadelphia Mint to San Francisco. And, we're also including the 1976 3-piece Silver Proof Set to make your collection virtually complete. Each year's coins come in original government packaging.
