Collectible coins encompass a range of numismatic items, including historical coins, commemorative pieces, and private or regional issues. In the United States, post-1776 coins include a variety of denominations, such as the One Dollar coin, which has seen multiple designs and series since its introduction. Coins minted from 1790 onward include both government-issued currency and private tokens, reflecting the evolving economic landscape and regional identities of the time. Collectors often seek these coins for their historical significance, rarity, and artistic design.
