If the reported numbers are correct, 203 4c Inverts were released, both with and without the overprint. An unknown quantity of the 4c Pan-American Invert was overprinted with small "Specimen" overprints. Some examples, both with and without the overprint, were given away by Third Asst. Postmaster General Edwin C. Madden. When postal authorities learned of the practice, they destroyed 194 copies and put one pane of 100 into the official archives. At a later date, 97 of these were later traded for rarities missing from the archives. The gum on the majority of stamps without "Specimen" overprint was disturbed due to their removal from mounting paper.
