Canada #1164 38c Queen Elizabeth II 1988-1991 Wildlife and Architecture Issue, a VFNH Pair Showing Significant Misperf, on DF/LF-fl Paper
A well centered (top to bottom) VFNH pair of the 38c Queen Elizabeth II stamp from the 1988-1991 Wildlife and Architecture Issue, printed on DF/LF-fl Harrison paper, showing a dramatic misperf, in which the vertical perforations are shifted 3 mm to the left. This paper type is unlisted in Unitrade, but the fluorescent flecks that make it appear LF are distinct and clearly visible.
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 $25-$30 each, so this pair should be worth about $50-$60. The pair offered here grades 80 as follows:
Paper freshness: 5/5
Absence of visible paper flaws: 5/5
