2c Deep Rose, Ty. Ia,
Imperforate, Schermack Ty. III Private Perforation (482A). Schermack
perfs visible at left, neat wavy-line machine cancel, characteristic rich
color, centered to bottom right, light diagonal creaseFINE APPEARANCE. ONE OF THE RAREST 20TH CENTURY STAMPS, WITH ONLY 38 EXAMPLES RECORDED (ALL BUT ONE CANCELLED).
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 census of Scott 482A as published in our Zoellner catalogue and available at our website at: http://SiegelAuctions.com/enc/census/482A/482A.htm records the unique pair, three covers, one unused single and 32 used singles for a total of 38 stamps. Most examples are either cut well into the design or have the Schermack perfs trimmed away on one side.
