15c Pale Ultramarine, Bluish (366). Bright color, oval cancel, centered to right, small crease a bottom right

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

According to Johl-King and Boggs, 15c Bluish Paper stamps were discovered in the post office in Buffalo in January 1911. The rarity of the 15c Bluish Paper 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.

Census No. 366-CAN-07. With 1999 P.F. certificate
