Canada #1165 38c Parliament Buildings 1988-1991 Wildlife and Architecture Issue, a VFNH Single Showing Significant Misperf, on NF/LF Slater Paper
A VFNH single of the 38c Parliament Buildings stamp from the 1988-1991 Wildlife and Architecture Issue, printed on NF/LF Slater paper, showing a significant misperf, in which the horizontal perforations have been shifted 4 mm downwards. The NF/LF paper is not listed in Unitrade, but comparison with the normal NF/DF paper reveals a distinct difference in the brightness of this paper.
On this issue paper fluorescence has been completely ignored because the perception is that all the stamps are on dull paper. However, this is a bit of an oversimplification, as the pictures of some of the low value stamps will show. While it is true that the coated Slater, Harrison, Rolland and Peterborough papers are generally dull on the face, or non-fluorescent on the face, stamps on Coated Papers Paper are truly "dead" on the face most of the time and are much darker under UV than the stamps on any other paper. On the back, the papers vary from NF which is quite greyish to DF cream to a very light low fluorescence on some of the Harrison papers.
Unitrade does not list misperfs, but they typically sell for $30-$35 each, so this stamp should be worth about $30. The stamp offered here grades 80 as follows:
Paper freshness: 5/5
Absence of visible paper flaws: 5/5
