Collectible coins encompass various types, including historical coins, commemorative issues, bullion, and error coins. Within the context of the United States, coins often feature designs that celebrate important events, figures, or cultural milestones. Medallic Art Medals, created by specialized minting companies, often serve as art pieces or awards, distinct from currency. Coins from 1938 may include notable issues such as the Jefferson Nickel, which introduced the depiction of Thomas Jefferson, and can be sought after by collectors for their historical significance and collectible value. The term "unknown" may refer to coins or medals whose origin, rarity, or value has not yet been established in the numismatic community.
