Collectible coins include various types, such as the United States Jefferson Nickel, which has been minted since 1938. The 2006 San Francisco minting of the Jefferson Nickel is particularly notable for its proof and uncirculated versions. Five Cents coins, often referred to as nickels, include both the traditional nickel and the Half Dime, which was used before the nickel was introduced. Coin collectors often seek specific mint marks, years, and conditions, making variations like the 2006 San Francisco version valuable to collectors.
