Collectible coins encompass a variety of types, often categorized by their historical significance, rarity, and aesthetic appeal. The United States five cents nickel, known as the Jefferson Nickel, was first issued in 1938 and is named after President Thomas Jefferson. The half dime, an earlier denomination, was minted from 1792 to 1873, initially in silver. The 1975 San Francisco minting of the Jefferson Nickel is notable for its unique proof and uncirculated coin variations, appealing to collectors for its limited production and quality. Collectors often seek these coins for their numismatic value and historical context.
