Collectible coins include various types such as historical coins, commemorative coins, and bullion coins. In the United States, the five-cent coin, commonly known as the nickel, has been in circulation since 1866. One notable variety is the Jefferson Nickel, introduced in 1938, which features a portrait of Thomas Jefferson. The 1955 Jefferson Nickel is particularly sought after by collectors, especially in high-grade conditions, due to its historical context and relatively limited production compared to other years. The Half Dime, once a commonly used coin, is a type of silver coin that was minted before the nickel became prevalent.
