The following half dollar is believed to have been struck in the 1860s from dies sold by the mint as scrap metal and was probably struck by Joseph Mickley or Montroville Dickeson. It is a muling of the Overton 110 obverse of 1809 with the Overton 110 reverse of 1810. It is one of 2 confirmed examples.
According to the ANR 7/05 sale where the illustrated piece appears, both dies are in the latest die states and the reverse shows rust especially near "OF" in "UNITED STATES OF AMERICA". These dies still exist today in private hands.
