Proof sets offer the collector a chance to enjoy United States coins at their finest. It's no wonder they've reached new heights of popularity in recent years. In this detailed book, numismatic writer David W. Lange offers a definitive history of the United States Mint's Proof sets. They're all here, from the vintage years of 1936 to 1942, through the classic years of 1950 to 1964, the Special Mint Sets of 1965 to 1967, modern sets of 1968 to 1998, and the 50 State Quarters Proof Sets starting in 1999.
