The United States Mint released the 1st official "Uncirculated" Mint set in 1947. It was introduced to give coin collectors the opportunity to acquire ALL denominations and mints that were released into circulation per year, per coinage issue. Unlike the Proof Sets, these are normal coins intended for circulation. The "Official" packaging is the United States Mint's stamp of authenticity as to the condition of the coins.

This 1967 United States Mint set is the 9th year of issue. In 1965 the U.S. Mint reorganized it's collectible coinage division. It moved its Proof Set manufacturing from the Philadelphia Mint to the fabled San Francisco Mint. Regular production was "re-opened" in 1968. Between 1965 and 1967 the U.S. Mint didn't create a Mint Set or Proof Set....instead it created a hybrid called the "Special Mint Set", aka: "SMS" for short. This SMS set includes a single Cent, Nickel, Dime, Quarter, and Half Dollar.

The 1967 SMS set ranks #29 in mintage, with 1,863,344 struck.

Uncirculated sets sold by the US Mint from 1947 to 1958 contained two examples of each regular issue coin. These were packaged in cardboard holders that did not have a protective seal over the coins. Since 1959 the sets have been sealed in a protective plastic envelope. No official US Mint sets were issued in 1950, 1982 and 1983.
