EXTREMELY FINE GEM. WITHOUT QUESTION THIS IS THE FINEST USED IMPRINT SINGLE OF THE 12-CENT 1851 ISSUE. A REMARKABLE STAMP.
Our informal census of imprint copies of Scott 17 contains only six examples, including four with imprint at left and two with imprint at right. Of these, only three are thought to be sound. The only other example located in Power Search was sold in 1968. The example offered here, showing a significant portion of the imprint (as opposed to only part at top or bottom) is very desirable.
Ex Koppersmith, Klein and our "J & J" auction. With 1988 P.F. and 2011 P.S.E. certificates.
FRESH AND EXTREMELY FINE. AN ABSOLUTELY STUNNING USED PAIR OF THE 12-CENT 1851 ISSUE ON VERY THIN PAPER.
The thin papers are often associated with Part India. The Part India is described by Ashbrook as "undoubtedly from the very first impressions from the Twelve Cent plate. The engravings are very sharp and resemble die proofs or plate proofs on India. The shades of both these items are of the earliest known, the distinctive grayish."
Ex Klein and Wagshal. Light purple backstamps. With 1989 and 2010 P.F. certificates. Scott Catalogue has just listed this variety for the first time, starting with the 2012 U.S. Specialized Catalogue. Scott Retail as singles.
FINE APPEARANCE. AN EXTREMELY RARE EXAMPLE OF THE 12-CENT 1851 ISSUE WITH THE DESIGN PRINTED ON BOTH SIDES. ONE OF THE GREAT RARITIES OF THE 1851 ISSUE. ONLY TWO ARE RECORDED.
Engraved stamps printed on both sides usually have a poor impression on one side and a second, complete impression on the other. They probably occurred when a sheet was printed without proper moistening, which prevented the paper from picking up the ink in the recessed lines of the engraved plate.
Our list of printed-on-both-sides stamps is included as an appendix to this catalogue. The variety is known on the three denominations issued in 1851 -- 1c, 3c and 12c -- but not on the imperforate stamps issued in 1855 (10c) and 1856 (5c).
Reports have varied as to how many copies of the 12c 1851 printed on both sides are known. Brookman reported that he knew of four. However, we have only been able to locate two complete stamps, and this is the number widely used by students today. None is known unused. The other copy, ex Ishikawa, is shown below.
Offered in our 1967 and 1991 Rarities sales. Ex "J & J" Collection.
