EXTREMELY FINE GEM. A BEAUTIFUL AND RARE VERTICAL PAIR OF THE 5-CENT NEW YORK POSTMASTER'S PROVISIONAL WITH SMALL "A.C.M" INITIALS WITH PERIODS.
A number of factors makes this item rare. Vertical pairs are much scarcer than horizontal. Philip T. Wall estimated that only 25 of the former exist versus 150 of the latter (he was of course unaware of the Frelinghuysen collection, which added to that supply). The black pen cancel is also scarcer than the blue pen normally seen. Combining these factors with the scarcer "A.C.M." initials and choice condition makes this a very desirable pair.
Ex Frelinghuysen. With 2012 P.F. certificate
