The Jefferson Nickel is a five-cent coin that has been issued by the United States since 1938, featuring a portrait of Thomas Jefferson on the obverse and Monticello on the reverse. The 1957 Jefferson Nickel is part of a series known for its metal composition of 75% copper and 25% nickel. Collectors often seek variations in mint marks, such as the "D" for Denver and "S" for San Francisco, which can affect rarity and value. The Half Dime, a historical coin worth five cents, was minted until the late 19th century, while the term "nickel" initially referred to various five-cent coins, including earlier versions prior to the Jefferson design.
