Collectible coins encompass a wide range of numismatic items, including historic currency, commemorative pieces, and specific denominations that hold particular value to collectors. The Three Dollar gold piece, minted in the United States from 1854 to 1889, is notable for its rarity and distinct design, which features the iconic Liberty head. The Braided Hair Cent, minted in 1850, represents one of the later designs of the large cent series, known for its unique depiction of Liberty with braided hair, making it a sought-after item in numismatics. Both types of coins reflect significant periods in American minting history and attract collectors for their artistic and historical significance.
