6c Dull Brown, USIR Watermark (271a). Showing clear "I" of watermark, deep rich color, bold New York double oval cancel

EXTREMELY FINE. EASILY ONE OF THE FINEST RECORDED EXAMPLES OF THE 6-CENT USIR WATERMARK IN EXISTENCE. ONLY FIFTEEN USED COPIES HAVE BEEN CERTIFIED BY THE PHILATELIC FOUNDATION.

Unlike its more common 8c counterpart, the 6c is an extremely rare stamp. Our recently updated census contains only seven unused and 22 used examples of this rarity which have been certified as genuine by the P.F. Of the 22 used copies certified by the Philatelic Foundation, sixteen have perfs either close or touching the design (including both copies in the only recorded used pair and one with straight edge)

With 1986 and 2002 P.F. certificates
