Collectible coins encompass a wide range of numismatic items, including historical currency, commemorative pieces, and specific mint errors that appeal to collectors. The Braided Hair Cents, minted in the United States from 1840 to 1857, feature a design with a braided-haired lady Liberty and are notable for their intricate detail and historical significance. The 1849 Five Dollar gold coin, part of the Liberty Head series, is also highly sought after due to its age and connection to the California Gold Rush. Collectors often seek specific issues, grades, and rarities within these categories for investment and pastime purposes.
