On August 17, 1805, among Sacagawea's people, the Shoshone Indians, Meriwether Lewis wrote:

We next inquired who were chiefs among them. Cameahwait pointed out two others whom he said were Chiefs. We gave him a medal of the small size with the likeness of Mr. Jefferson, the President of the U' States, in relief on one side and clasped hands with a pipe and tomahawk on the other. To the other Chiefs we gave each a small medal . . . which were struck in the Presidency of George Washington, Esqr. We also gave small medals of the last description to two young men whom the 1st Chief informed us were good young men and much respected among them.
