Collectible coins can include a variety of pieces, such as commemorative coins, rare mintages, error coins, and historical currency. The United States has produced many collectible coins, including the Fifty Cents denomination, specifically the Kennedy Half Dollar, which was first minted in 1964. The 1999 San Francisco Mint issues of the Kennedy Half Dollar were released as part of a special set, which is sought after by collectors due to its limited production and the significance of the Kennedy legacy. Collectors often seek these coins for their historical value, numismatic interest, and potential for appreciation in value.
