Collectible coins encompass various types, including numismatic coins, which are valued not just for their monetary worth but for their historical significance, rarity, and condition. Among U.S. coins, the One Cent Penny is notable, particularly for its early issues and varying designs. Counterstamped coins, which feature additional marks or inscriptions applied after minting, can also be significant to collectors, reflecting personal or commercial usage. Coins from as early as 1820 can hold considerable value, especially if they possess unique features or limited mintage.
