The second small-size U.S. dollar coin honored Lewis and Clark’s young Shoshone guide. Struck in manganese-brass over a copper core, the coins’ golden-yellow color led them to be called “golden dollars.” Glenna Goodacre’s obverse depicts Sacagawea with her infant son, Jean Baptiste. liberty is inscribed above the pair, with in god we trust on the left and the date at right. The reverse by Thomas D. Rogers Sr. bears a soaring American eagle and the motto e pluribus unum. Encircling the design are 13 stars, united states of america and one dollar. In 2009, the Sacagawea dollar became the new Native American dollar series. It continued to be struck in manganese-brass over a copper core. And it kept Glenda Goodacre’s obverse design showing Sacagawea and her infant son, Jean Baptiste. But each year a new reverse honors Native Americans and their contributions. Edge inscriptions bear each coin's date, mint mark and the motto e pluribus unum.
