(476A). Position 32 from Plate No. 6911, Mint N.H., very deep and
intense color on bright white paper, sharp proof-like impression,
well-centered for this difficult issue with wide margins on all
sidesEXTREMELY FINE. EASILY ONE OF THE FINEST EXAMPLES OF THE VERY RARE 30-CENT PERF 10 WASHINGTON-FRANKLIN ON UNWATERMARKED PAPER. A REMARKABLE STAMP IN TERMS OF COLOR, CENTERING, FRESHNESS OF PAPER AND CENTERING FOR THIS ISSUE.
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.
