EXTREMELY FINE APPEARING EXAMPLE OF THE 1922 5-CENT PERF 10 AT TOP. ONLY TWELVE USED SINGLES ARE CONTAINED IN OUR RECORDS.
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.
