25c Yellow Green, Perf 10 at Right (568c). Deep rich color and proof-like impression, neat strike of “1” oval grid cancel, small crease at top right, tiny pinhole at right center FINE APPEARANCE. A RARE EXAMPLE OF THE 1922 25-CENT NIAGARA FALLS PERFORATED 10 ON ONE SIDE. ONLY SIX USED SINGLES ARE RECORDED. ONE OF THE RAREST OF THE PERFORATED 10 ON ONE SIDE VARIETIES. At a certain point during production one of the perforating wheels became defective. In the course of repairs part of one perforation wheel was inadvertently changed from Perf 11 to Perf 10. Based on the physical evidence of surviving copies, this was the nineteenth row of pins on the wheel. Many examples of the Perf 10 on One Side rarities show transitional perfs from 10 to 11 or from 11 to 10. This is because the out-of-gauge perforation pins would frequently cross the span of more than one stamp, depending on where the wheel contacted the sheet. The Perf 10 on One Side varieties span both the 1917 Washington-Franklin and 1922-23 Issues. It is interesting to note that, apart from the 2c, there is no duplication of denomination between the issues. This would seem to indicate that the improperly repaired wheel was in use for only a short period of time, as there was little overlap in production of the issues. Based on dates of issue of the basic stamps, this probably occurred early in 1923. Unlike the other flat plate perf 10 on one side varieties, the 25c is perforated 10 at either left or right. This is due to the horizontal orientation of the stamp. Our census of Scott 568c, illustrated below and available at our website at http://www.siegelauctions.com/dynamic/census/568c/568c.pdf , records six used singles, one unused single and two unused in a block of eight.
