Collectible coins encompass a wide range of numismatic items, including historical pieces, commemoratives, and error coins. In the United States, five-cent nickels, such as the Jefferson Nickel, first minted in 1938, have become popular among collectors. The San Francisco mint has produced various special edition coins over the years, including proof and uncirculated versions, which may hold additional value. The half dime, a denomination prior to the nickel, was struck from 1794 to 1873, making it a notable subject for collectors interested in early American currency.
