Collectible coins encompass a variety of types, including numismatic coins, bullion coins, and commemorative coins, each appealing to different collectors for reasons such as historical value, rarity, or precious metal content. The Jefferson Nickel, introduced in 1938, features a portrait of Thomas Jefferson on the obverse, and many collectors focus on specific years, such as the 1968 issue minted in San Francisco. Notably, the 1968 San Francisco Jefferson Nickels are part of a set that includes both regular circulation coins and proof versions, which are sought after by collectors for their quality and finish. The Half Dime, a historical coin worth five cents, was issued in the early years of the United States and has become a popular subject among numismatists, interested in its unique place in American coinage history.
