1968-1970 Proof Sets

1968 marked the resumption of standard proof set production from the United States Mint. The previous three years saw no proof or mint sets produced by the U.S. Mint which instead offered a product called Special Mint Sets. The Special Mint Sets were struck in San Francisco.

It also really marked the beginning of the modern era of proof sets. Beginning with 1968, the coins included as part of the proof sets were struck at the United States Mint’s facility in San Francisco, just as they are today. The coins of the set were also encased in a special plastic holder and similar to today’s product and placed in a cardboard box.

These sets also marked both the beginning and the end of certain specifications as they related to the included Kennedy Half Dollar. The 1968 Proof Set marked the first time a 40% silver Kennedy Half Dollar was included as part of the set. The 1964 Proof Set (the last time such a set had been issued) contained a 90% silver Kennedy Half Dollar. After 1970, Kennedy Half Dollars included as part of standard proof sets were struck from a clad composition.
