Collectible coins, such as those from the United States, include various denominations and series. The five-cent nickel, specifically the Jefferson nickel, was first minted in 1938 and features a portrait of Thomas Jefferson on the obverse and Monticello on the reverse. The 1949 Jefferson nickel, minted in Denver, is a notable example and can be sought after by collectors for its historical significance and minting details. The term "halfdime" historically refers to coins valued at half a dime, often representing earlier types of U.S. coinage. Collectors value these coins based on rarity, condition, and historical context.
