The Golden Dollar is a clad coin and the alloy layers on each side of the core are manganese brass, a golden-colored material composed of 77% copper, 12% zinc, 7% manganese, and 4% nickel. Taking account of the copper core, the overall composition of the Golden Dollar is 88.5% copper, 6.0% zinc, 3.5 % manganese, and 2.0% nickel. The coin’s composite construction provides security features that allow machines to distinguish it from slugs, tokens, and foreign coins.
