Collectible coins, particularly in the context of the United States, include various denominations created throughout history. The five-cent nickel, commonly known as the Jefferson Nickel, was first minted in 1938 and features a portrait of Thomas Jefferson. The Half Dime, a silver coin produced until the 1870s, was also used during earlier periods. The 1966 Jefferson Nickel, produced at the San Francisco Mint, is notable for its unique design and minting marks, appealing to collectors due to its historical significance and limited production.
