Gold dollars were a series of small denomination coins minted by the United States from 1849 to 1889. The 1876 Gold Dollar, produced in Philadelphia, features the image of Liberty on the obverse and a wreath on the reverse. These coins were primarily made of 90% gold and 10% copper, weighing approximately 1.5 grams. The 1876 edition is particularly sought after by collectors due to its historical significance and aesthetic appeal.
