Collectible coins encompass a wide range of numismatic items, including various denominations and types that hold historical and aesthetic value. The Five Cents Nickel, commonly known as the Jefferson Nickel, was first issued in 1938 and features a portrait of President Thomas Jefferson. The Half Dime, a coin worth five cents, was produced by the United States Mint primarily in the 19th century. The San Francisco Mint is known for producing proof coins, including Jefferson Nickels from specific years like 1991, which are sought after by collectors for their quality and limited mintage.
