Collectible coins encompass a variety of types, including historical, commemorative, and bullion coins, each with distinct characteristics and values. In the United States, the nickel denomination includes the five-cent coin, frequently referred to as the "nickel," which has undergone several design changes. One notable type is the Buffalo nickel, minted from 1913 to 1938, with the 1930 San Francisco minting being particularly sought after by collectors due to its lower mintage and unique design featuring an American Indian on the obverse and a buffalo on the reverse. Another collectible variant of the five-cent coin is the Half Dime, which was issued prior to the nickel's introduction.
