The Sacagawea Dollar introduced a new composition developed by the United States Mint to have a distinctive golden color while maintaining the same electromagnetic signature as the previous series. The composition includes a core of pure copper with an outer layer of manganese-brass, consisting of 77% copper, 12% zinc, 7% manganese, and 4% nickel. Including both the core and outer layers, the overall composition is 88.5% copper, 6% zinc, 3.5% manganese, and 2% nickel.
The coins have a diameter of 26.5 mm and weight of 8.1 grams with a plain edge. During the course of the series, coins were struck at the Philadelphia, Denver, and San Francisco Mint facilities. The mint mark location is on the obverse of the coin beneath the date.
