Collectible coins include a variety of types, such as historical coins, commemorative issues, and specific denomination series. The Jefferson Nickel, produced by the United States since 1938, features Thomas Jefferson on the obverse and Monticello on the reverse. The 1956 Jefferson Nickel is notable for various mint marks, with the Philadelphia mint producing a significant number without a mint mark. Additionally, the Half Dime, which was in circulation prior to the Nickel, is a historical denomination reflecting the evolution of U.S. coinage.
