30c Orange Red, Perf 10
(476A). Position 83 from Plate No. 6911, Mint N.H., very deep and
intense color, sharp proof-like impression on bright white paper, unusually
choice centering for this difficult issueFRESH AND EXTREMELY FINE. AN OUTSTANDING MINT NEVER-HINGED EXAMPLE OF THE VERY RARE 30-CENT PERF 10 WASHINGTON-FRANKLIN ON UNWATERMARKED PAPER.
In an article in Philatelic Opinions V published by the Philatelic Foundation, William T. Crowe, head of the Expert Committee, discusses the discovery of this rare stamp and how it might have been issued. The production of Scott 476A occurred during the period of transition from gauge-10 perfs to gauge 11. Bureau records do not list a 30c printing on unwatermarked paper that was perforated 10, but the existence of two certified panes--one bottom-right pane from Plate 6917 and one top-right pane from Plate 6911--is evidence that the combination of new unwatermarked paper and old 10-gauge perfs occurred, even if inadvertently. Stamps from these two panes (200 total), two left sheet-margin blocks of four and a bottom plate no. 6914 single, none of which have any trace of watermark, are the only accepted examples of Scott 476A.
The position just above this one, with similar centering, realized $12,000 in our Piedmont sale in February 2002. With copy of 1984 P.F. certificate (Image)

This 50c stamp was only in production for a very short period of time. It was actually released only three weeks prior to the beginning of the new Perf 11 series and was only used for a short period of time before being superseded by the new issue.
