EXTREMELY FINE. A SCARCE USED EXAMPLE OF THE 1917 PERF 11 5-CENT ERROR. THIS IS EXTREMELY DIFFICULT TO FIND AS A SOUND AND CENTERED USED STAMP.

During the course of production of the normal 2c from plate 7942, three positions were noted to be defective. The plate was returned 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 Perf 10, Imperforate and Perf 11 (Scott 467, 485 and 505). The imperforate is not known used. The Perf 10, Scott 467, is scarcer than the Perf 11 offered here, but both are very difficult to find in sound and centered used condition. The last time we offered a used example in any condition was in 2004.

VERY FINE APPEARANCE. A RARE EXAMPLE OF THE 6-CENT 1917 ISSUE PERF 10 AT TOP OR BOTTOM. ONLY 20 USED EXAMPLES ARE RECORDED IN OUR CENSUS. OF THESE, ONLY SEVEN SINGLES AND TWO IN A BLOCK HAVE REGULAR CANCELLATIONS, AND OF THESE ONLY THE TWO IN THE BLOCK ARE COMPLETELY SOUND.

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 20 used copies and one unused example. Of the 20 used copies, only seven singles and two in a block have regular cancels -- the others are precancelled. Of these seven, three have straight edges and the others have flaws ranging from creases to "defective".

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.

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.

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).

FINE. ONE OF ONLY TWO SOUND REGULARLY-CANCELLED EXAMPLES OF THE 1917 9-CENT PERF 10 AT TOP OR BOTTOM IN EXISTENCE. A GREAT RARITY.

Our census of Scott 509a, available at our website at http://siegelauctions.com/dynamic/census/509a/509a.pdf , contains a total of 27 used and one unused example of this rarity. Of the 27 used copies, fully 22 are precancelled. Only five have regular cancels. Of these five only two are sound (the copy offered here and no. 21) and both have similar centering.

VERY FINE. A RARE BLOCK OF FOUR CONTAINING ONE STAMP PERF 11 AT BOTTOM AND ANOTHER WITH TRANSITIONAL PERFORATIONS FROM 10 TO 11. USED MULTIPLES OF THIS VARIETY ARE RARE.

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

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.

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.

VERY FINE APPEARANCE. ONE OF ONLY THREE EXAMPLES OF THE 1917 20-CENT PERF 10 AT TOP OR BOTTOM VARIETY WITHOUT A PRECANCEL. NONE IS KNOWN UNUSED. ONE OF THE GREAT RARITIES OF THE ISSUE.

Our census of Scott 515d, available at our website at http://siegelauctions.com/dynamic/census/515d/515d.pdf , contains a total of ten used copies. None is known unused. Of the ten copies only three have regular cancels, including one with a bruststroke and one with a boxed cancel. This is the finest of the three. One of the three has a boxed cancel and the other has a heavy brush stroke cancel. We consider this example to be desirable both for the size of its margins and for the attractive handstamp cancel.

FINE APPEARANCE. THIS IS ONE OF TWO USED EXAMPLES AND THE ONLY REGULARLY-CANCELLED EXAMPLE OF THE 1917 30-CENT PERF 10 AT TOP OR BOTTOM. ONE OF THE GREATEST RARITIES OF THE ISSUE.

Our census of Scott 516a, available at our website at http://siegelauctions.com/dynamic/census/516a/516a.pdf , contains three unused examples, the handstamp-cancelled copy offered here and one with a precancel, for a total of five copies. This is the only copy with a regular cancel that can be confirmed as having gone thru the mail. This is also the only used example we have offered since keeping computerized records.

Census No. 516a-CAN-01. With 1970 and 2009 P.F. certificates. Scott Catalogue has not adjusted the used price for this rarity in line with others of the issue, probably because none has come to market in over a decade. (Image)
