Collectible coins, or numismatic coins, are typically valued for their rarity, historical significance, and condition, rather than their face value. The United States has produced a variety of collectible coins, including the 1 One Dollar denomination, which has various designs throughout its history. The Coronet Head Cents, minted from 1816 to 1857, feature a design by famed engraver Christian Gobrecht. An example from 1824 was produced at the Philadelphia Mint, reflecting early American coinage and appealing to collectors interested in early U.S. history.
