In 1840 John Henry Moore reported from the Upper Colorado River that among the Indians killed in October was a very old man who wore a “silver medal, about an eighth of an inch in thickness and two and a half inches in diameter, one side of which presents a profile, in relief, of James Madison, with the words ‘James Madison, President of the United States, 1809.’ The reverse presents clasped hands with the calumet and tomahawk, and the words ‘peace and friendship.'”
