Sacagawea Dollar
Sacagawea Dollar Coins
The Sacagawea Golden Dollar coins debuted in January 2000. The new dollar coin replaced the Susan B. Anthony dollar coin, which had circulated since 1979.
Because demand had increased for a dollar coin in commerce, the government's supply of SBA dollars was nearly exhausted, creating a need for a new dollar coin that would be easily distinguishable from other change.
The overall composition of the new Sacagawea 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.
