Beginning in 1936, the U.S. Mint began producing proof coins again. Proof coins through 1942 could be ordered individually from the mint. Because of this the lowest mintage for any denomination (cent through half dollar) determines the total number of complete sets that can exist.
From late 1955 until 1964 the Mint packaged Proof coins in a flat, transparent cellophane holder. These sets are referred to in the industry as flat packs.. There were no Proof sets issued in 1965, 1966 and 1967. In these years the mint produced Special Mint Sets.
