EXTREMELY FINE. A RARE INTACT SHEET OF 400 OF THE 5-CENT IMPERFORATE ERROR. LESS THAN 50 SHEETS WERE RELEASED TO THE PUBLIC.
During the course of production of the normal 2c plate No. 7942, three positions were noted to be defective. The plate was sent back to the siderographer, who burnished out the three positions and mistakenly re-entered them using a transfer roll for the 5c stamp. The error passed unnoticed and the sheets were issued to the public both Perf 10, Imperforate and Perf 11 (Scott 467, 485 and 505). The imperforate is by far the rarest of the three, having come from a group of fifty sheets released to the public.
Scott Retail as single error in Mint N.H. block of nine and double error in Mint N.H. block of twelve, with no additional catalogue value added for the plate blocks and 2c stamps and no premium added for the intact multiple, is $85,000.00
