United States Mint introduced The Eagle ($10 US Gold Coins) as a base-unit of denomination issued specially for gold coinage only (the eagle was the base-unit of denomination in gold) and the eagle was the largest of the four main decimal base-units of denomination (the cent, the dime, the dollar, and the eagle, where a dime is 10 cents, a dollar is 10 dimes, and an eagle is 10 dollars) used for circulating coinage in the United States prior to 1933, the year when gold was withdrawn from circulation.
