VERY FINE APPEARANCE. AN EXCEPTIONALLY RARE UNUSED EXAMPLE OF THE 1917 12-CENT PERF 10 AT BOTTOM. ONE OF ONLY FOUR UNUSED STAMPS RECORDED IN OUR CENSUS.
Our census of Scott 512b, available at our website at http://siegelauctions.com/dynamic/census/512b/512b.pdf , contains only twelve used and four unused examples of this rarity (including a pair).
Census No. 512b-OG-04. With 2013 P.F. certificate
EXTREMELY FINE AND EXCEEDINGLY RARE USED SHEET-MARGIN BLOCK OF THE 2-CENT TYPE VII OFFSET IMPERFORATE ISSUE.
According to Armstrong, the imperforates were issued to satisfy the needs of the last remaining private coil manufacturer. The Mail-O-Meter Company merged with the Schermack Company and so these issues are also known with the Schermack Type III perforations, such as are also seen on Scott 314A and 482A. However, a small supply of the imperforate 2c Type VII stamps without Schermack perfs did reach the public.
Our informal review of auction catalogues and the records of the Philatelic Foundation found four blocks of four and nine pairs, of which only four are sound. This is the first block we have offered since our 2001 Twigg-Smith sale.
The Scott Catalogue pricing is in error as it values two used pairs higher than a used block -- which is considerably rarer. Scott Retail as two used pairs
