Collectible coins encompass a wide variety of types, including historical, commemorative, and error coins. The United States five-cent nickel is a prominent example, with the Jefferson Nickel being introduced in 1938. The term "half dime" refers to earlier silver coins valued at five cents, minted until 1873. In 1991, the U.S. Mint continued producing Jefferson Nickels, showcasing designs that honor Thomas Jefferson, the third president. Collectors often seek specific mintages and variations, particularly those with errors or unique attributes.
