VERY FINE. AN EXTREMELY RARE MIXED FRANKING WITH THE U.S. 3-CENT 1851 ISSUE AND CANADA 3-PENCE 1852 BEAVER ISSUE--NOT ACCEPTED FOR POSTAGE IN CANADA AND MARKED AS AN UNPAID LETTER. ONLY TWO SUCH MIXED FRANKINGS ARE RECORDED.
The rate treaty between the U.S. and Canada was 10c. The 6d and 10cts handstamps on this cover indicate that Canada disregarded the 3c U.S. stamp and did not give partial credit to the 3p Beaver stamp, treating the cover as completely unpaid (in any event the postage does not add up to 10c). However, as Stanley B. Ashbrook wrote on back and discussed in his Special Service, the lack of any New York due markings indicates that the U.S. accepted the letter as paid. A similar cover with a 3c 1851 and Beaver stamp, treated in the same way in Canada and the U.S., was offered in our 1970 Rarities and 1992 Kapiloff sales (and is also illustrated and discussed in Ashbrook). Approximately six examples of the 3c 1851 used from Canada are known, making them even rarer than the 1847 Issue used from Canada. Of those, only two 3c 1851s are mixed frankings with Canadian stamps.
Discussed and illustrated in Ashbrook's Special Service (No. 68, p. 552, photo 273) and Boggs. Ex Caspary, Krug and Baker.
VERY FINE. A SPECTACULAR AND UNIQUE USE OF A BLOCK OF FOUR OF THE 3-CENT 1851 ISSUE, APPLIED IN CANADA ON A COVER TO THE UNITED STATES AND ACCEPTED AS FULLY PAID BY BOTH.
In contrast to the mixed-franking cover offered in lot 259, this cover, which overpaid the 10c treaty rate, was accepted in Canada as fully prepaid, even though franked entirely with U.S. stamps. Approximately six examples of the 3c 1851 used from Canada are known. This is the only cover with a block and, in our opinion, is one of the most outstanding cross-border covers from any period.
