Collectible coins encompass various types, including commemorative, historical, and bullion coins. The Jefferson Nickel, introduced in 1938, features Thomas Jefferson and is known for its distinctive design. The 1978 Denver Mint struck Jefferson Nickels are part of the regular series, made primarily from a cupronickel alloy. The five cent denomination, commonly referred to as the nickel, has historical significance in American currency, and notable variations exist, particularly with error coins and special releases.
