1756 (post-1874) Colonel John Armstrong / Kittanning Destroyed Medal. Copy Dies. Bronze. 48 mm. Julian MI-33, Betts-400. MS-67 BN (NGC). Richly toned surfaces exhibit blended pale olive-gold highlights to dominant orange-brown patina. Smooth and satiny with razor sharp striking detail from the rims to the centers. The original dies for this type were brought to the United States Mint by Joseph Richardson circa 1800. The Mint produced restrikes from those dies from the earliest days of the 19th century through about 1874. At that time a new set of dies were introduced, the original ones having shown considerable evidence of failure even as early as the 1860s. The present example is a later impression from the copy dies, as evidenced by the prominent obverse border break from 9 oclock to 10:30, although the finish still points to a striking period during the late 19th century.
