Sale Number 1093, Lot Number 473, 1917-19 Perf 10 on One Side Varieties (Scott 506a-512b)6c Red Orange, Perf 10 at Bottom (506a), 6c Red Orange, Perf 10 at Bottom (506a)6c Red Orange, Perf 10 at Bottom (506a). Fresh color, light circular datestamp at right leaves most of design clearly visible, small corner crease and small crease, three short perfs not noted on certificate

VERY FINE CENTERING. ONE OF 20 RECORDED EXAMPLES OF THIS PERFORATION VARIETY.

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.

Our census of Scott 506a, available at our website at http://siegelauctions.com/dynamic/census/506a/506a.pdf , contains 19 used copies and one unused example. Of the 19 used copies, only seven singles and two in a block have regular cancels -- the others are precancelled. Only one of the handstamp-cancelled singles (with straight edge) and the two in the block are sound.

Census No. 506a-CAN-11. With 2003 P.F. certificate

EXTREMELY FINE. THIS MAY WELL BE THE FINEST EXAMPLE OF THE 1917 8-CENT PERF 10 AT TOP OR BOTTOM IN EXISTENCE. A PHENOMENAL RARITY.

Our census of Scott 508c, available at our website at http://siegelauctions.com/dynamic/census/508c/508c.pdf , contains sixteen certified and two uncertified examples of this rarity. Of these 18 copies only eight have regular cancels. Whittling the numbers down even further, three of the eight have faults, and only three of the five sound and handstamp/machine-cancelled copies could be considered well-centered (nos. 10, 15 and the example offered here).

Census No. 508c-CAN-06. Ex Grunin, Schilling, Zoellner, Blumenkopf and Natalee Grace. With 1998 P.F. certificate.

VERY FINE APPEARANCE. A RARE EXAMPLE OF THE 1917 12-CENT PERF 10 AT TOP. ONLY TWELVE USED EXAMPLES ARE KNOWN, AND THIS IS ONE OF ONLY FIVE EXAMPLES WITH A REGULAR CANCEL. A GREAT RARITY.

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. For some reason none is well-centered. Seven of the twelve used examples have precancels. Only one of the five with regular cancel is confirmed as sound (no. 8), but it is off-center in two directions. Two others (nos. 2 and 3) need to be reexamined as they have very old certificates -- one is from around 1950. The example offered here has margins wider than most and should be considered a very desirable example of this rarity.

Census No. 512b-CAN-01. Ex Schilling, Zoellner, Blumenkopf and Natalee Grace. With 1950 and 1998 P.F. certificates.
