Collectible coins, particularly in the context of the United States, include various denominations and historical issues. The 5-cent nickel, known as the Jefferson Nickel, was first introduced in 1938 and has undergone various design changes since. The 2018 Philadelphia mint version of the Jefferson Nickel features the classic depiction of Thomas Jefferson on the obverse and Monticello on the reverse. Additionally, the term "half dime" historically refers to a silver coin that was issued prior to the introduction of the nickel, highlighting the evolution of U.S. coinage. Collectors often seek out specific years, mint marks, and design variations to enhance their collections.
