Collectible coins can encompass a variety of types, including historical, commemorative, and denomination-specific pieces. The United States five-cent nickel, commonly referred to as the Jefferson Nickel, has been produced since 1938 and is named after President Thomas Jefferson. The 1973 San Francisco mint issuance of this coin represents a unique collectible due to its mint mark and possible variations, such as proof coins that were produced for collectors. Additionally, the half dime is a former denomination that was used in the U.S. prior to the nickel's introduction, adding further historical significance to the collection of American coins.
