VERY FINE AND CHOICE. ONLY TEN USED COPIES OF THE 15-CENT ON BLUISH HAVE BEEN CERTIFIED BY THE PHILATELIC FOUNDATION. A GREAT RARITY.

According to Johl, the 15c stamps were discovered in the post office in Buffalo N.Y. The rarity of the 15c on Bluish in used condition is often overlooked by collectors, probably because it is fairly plentiful in unused condition. Our census, available at our website at http://siegelauctions.com/dynamic/census/366/366.pdf , records only ten used copies. None is known on cover. Another has a certificate declining opinion as to whether the cancel is contemporary, and two others (not included) need to be reexamined for genuineness. Of the confirmed copies only two or three are sound. The sound example offered here is highly desirable.
