single, very deep and intense color, sharp proof-like impression on
bright white paper, typical centering for this rare stampFRESH AND VERY FINE. AN OUTSTANDING AND DESIRABLE SHEET MARGIN COPY 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 inadvertantly. Stamps from these two panes (200 total), and a bottom plate no. 6914 single, none of which have any trace of watermark, are the only accepted examples of Scott 476A.
Due to the color of the stamp and the nature of the watermark, it is often difficult to tell whether the 30-cent stamps are indeed on unwatermarked paper. The example offered here, with a sheet margin allowing for conclusive identification of the stamp as being on unwatermarked paper, is highly desirable.

2c Deep Rose, Ty. Ia,
Imperforate, Schermack Ty. III Private Perforation (482A). Tied by
"Chicago Ill. May 22, 1920 5 PM Join the Navy" slogan machine cancel on
small piece, deep rich color, centered to left as are virtually all
recorded examples, full and intact Schermack perforations at
rightVERY FINE AND CHOICE. ONE OF ONLY 39 RECORDED EXAMPLES OF THIS GREAT TWENTIETH CENTURY RARITY. THE ONLY RECORDED EXAMPLE ON PIECE -- A NEW ADDITION TO OUR CENSUS.
Scott 482A, like its more famous predecessor, Scott 314A, was issued imperforate by the Bureau of Engraving and Printing and sold to the Schermack Company for use in its patented stamp-affixing machines. The Schermack "Sealer and Stamper" machine typically applied stamps one at a time, and, in most cases, the hyphen-hole perfs on one side would be cut off. Unlike Scott 314A, the release of imperforate sheets printed from the experimental Type Ia plates escaped the notice of contemporary collectors, and, therefore, has a very small survival rate.
Our updated census of Scott 482A first published in the Zoellner catalogue records three covers, one unused single, a pair and 33 used singles for a total of 39 stamps. Most examples are either cut well into the design or have the Schermack perfs trimmed away on one side. The example offered here previously escaped our notice, as it has never received a Philatelic Foundation certificate and is not listed in any of our other sources.
