Collectible coins encompass a wide range of numismatic items that are valued for their historical significance, rarity, and condition. The "Three Dollar" gold coin, produced in various designs, was issued by the United States Mint from 1854 to 1889, with the 1848 Braided Hair Cent being an earlier example from a different denomination. The Braided Hair Cents, minted between 1839 and 1857, feature a design with a braided hair portrait of Liberty and are sought after by collectors for their artistic value and historical context. Both types exemplify the diversity within American coinage and the interests of numismatists in specific series or designs.
