"The 2014 Native American $1 Coin commemorates native hospitality ensuring the success of the Lewis and Clark Expedition. The reverse (tails side) design depicts a Native American man offering a pipe, while his wife offers provisions of fish, corn, roots, and gourds. In the background is a stylized image of the face of William Clark's compass highlighting "NW," the area in which the expedition occurred."
