Collectible coins, particularly from the United States, include a variety of denominations such as 1 cent (penny) and 50 cents (half dollar). The Special Mint Sets (SMS) were issued by the U.S. Mint in 1965, 1966, and 1967 as a response to the reduction in proof coin production during the transition to a new coinage. The 1965 Special Mint Set, produced in San Francisco, features a distinctive method of minting that results in high-quality finishes and is sought after by collectors for its limited availability and historical significance. These sets often include coins that were not released in standard circulation during that period.
