This artifact is a good excavated example of a small, cuff-size, general issue cast pewter button as worn on the United States Army enlisted uniform circa 1808 to 1830. Classified as a GI30b in Albert's reference book, this small one-piece 19-mm button features a face that depicts the raised letters "U.S." with a small six-pointed star between the letters. Button retains its shank which has been bent and turned back on itself. A wonderful excavated U.S. Army pewter uniform button from the early 1800s.
