Collectible coins encompass a wide range of types, including historical pieces, commemorative coins, and bullion. United States coins, particularly those minted before 1776, are highly sought after by collectors due to their rarity and historical significance. The 1P One Penny, though more common in British numismatics, highlights the broader interest in coinage from different cultures. The first known coinage in what would become the USA dates back to 1659, with the Massachusetts Bay Colony's pine tree shillings, marking an important development in colonial currency.
