Description & Analysis

In 1964, the United States faced a coinage shortage. Due to this, the mint ceased production of normal proof coins, which required significantly more work with die and planchet preparation. As a substitute, they created the Special Mint Set, which contained coins that weren't quite proofs, but were clearly of a higher quality than normal circulation coins. This allowed the mint to place more resources into producing coins for circulation. These special sets were issued in 1965, 1966 and 1967 before normal proof production started once more in 1968.
