FRESH AND FINE. AN OUTSTANDING EXAMPLE OF THE VERY RARE 30-CENT PERF 10 WASHINGTON-FRANKLIN ON UNWATERMARKED PAPER.
Despite the recent P.S.E. claim that a watermark has been "discovered" on one stamp from one of the 476A panes, the vestige of a watermark on the dandy roll used to make unwatermarked paper has been known to philatelists since 1918. The unwatermarked paper supplied to the Bureau for printings of sheets that were perforated gauge 10 and 11 is known to have had "ghost" watermarks where the brass pieces were removed. We currently side with the group of philatelists who believe that the 30c Perf 10 Unwatermarked, Scott 476A, was legitimately issued.
With 1984 P.F. certificate
