Since 2009, the reverse of the Sacagawea dollar has been changed yearly, with each design in the series depicting a different aspect of Native American cultures. From 2000 to 2008, the reverse featured an eagle design by Thomas D. The coin features an obverse by Glenna Goodacre. These coins have a copper core clad by manganese brass, giving them a distinctive golden color. The coin generally failed to meet consumer and business demands. The Sacagawea dollar (also known as the ' golden dollar') is a United States dollar coin introduced in 2000, but subsequently minted only for niche circulation from 2002 onward.
