The artwork on the Idaho 1/2 Goldback honors Sacagawea, an Agaidika Shoshone woman born near Lemhi Pass in what is now Idaho. She is depicted as the virtue Pietas, or Devotion. In 1805, Sacagawea traveled with the Lewis and Clark expedition to Lemhi Pass, serving as an interpreter and guide. Along the way, she carried her infant son, Jean Baptiste Charbonneau. Their route followed the Lolo Trail, which was a demanding path known to Indigenous peoples. In the artwork, the words “Lolo Trail” and the year 1805 are carved into rocks. She wears a traditional Shoshone dress, beaded belt, and tool bag. In the background, an Appaloosa mare and her foal stand together, mirroring Sacagawea's devotion to her child. The Bitterroot Mountains rise in the background as Lolo Creek winds through the valley. Idaho's state symbols surround the scene: white pine, huckleberries, and mountain bluebirds. Through her piety, Sacagawea helped guide one of the most important expeditions in American history. Her legacy is rooted in Idaho's land, its trails, and the enduring values that still define the state today. Inscribed along the bottom is the quotation: “Everything I do is for my people.”
