Collectible coins, such as those from the United States, include various denominations and types, each with distinct historical and numismatic significance. The 5-cent nickel, commonly known as the Jefferson Nickel, was first issued in 1938 and features a portrait of Thomas Jefferson. The 1951 Jefferson Nickel struck at the San Francisco Mint is particularly notable for its rare variants and potential collectible value, especially in high grades or specific mint marks. Additionally, the Half Dime, which was minted prior to the Nickel, is an earlier form of 5-cent coinage that appeals to collectors due to its historical context and limited mintage.
