Coins are tangible pieces of currency that serve as legal tender and are often collected for their historical significance, rarity, and intrinsic value. The United States Mint has produced various coin types, including the 1 One Dollar coin, which features different designs throughout its history. Gold Dollars, specifically minted from 1849 to 1889, include the 1885 Gold Dollar produced in Philadelphia, characterized by its small size and 90% gold content. Collectors often seek these coins for their aesthetic appeal, condition, and limited mintage.
