U S A – 1908, 1c Benjamin Franklin vertical pair – worth US.$.310,000

The pair of stamps depicting Benjamin Franklin in blue and green colors with a one cent denomination. These stamps are different from previous designs because they are printed on double line paper covered with the USPS (U.S. Postal Service) watermark. Since the letters were depicted across the entire sheet, very often only a portion of the watermark would appear on a stamp, usually in a backwards, sideways or topside position. An unused pair of the 1908 Benjamin Franklin stamps was sold for $310,000 at Robert.A.Siegel auction that took place in April, 2015.
