Collectible coins encompass various categories, including historical coins, error coins, and commemorative pieces. The five-cent nickel, also known as the Jefferson nickel, was introduced in 1938, featuring a portrait of Thomas Jefferson and a depiction of Monticello on the reverse. The half dime was produced from 1792 to 1873, initially made of silver and later in other metals. The San Francisco Mint, established in 1937, is known for producing limited edition coins, including special uncirculated and proof versions like the 1984 Jefferson nickel. Collectors often seek coins based on their rarity, condition, and historical significance.
