Canada #462iv (SG#585c) 10c Deep Yellow Green 1967-73 Centennial LF GW-fl Paper UL Blank PVA Gum VF-84 NH

A very well centered and very fine mint NH upper left blank corner block of the 10c deep yellow green Jack Pine stamp from the 1967-1973 Centennial Issue. Horizontal wove paper with no visible mesh or ribbing, and smooth colourless PVA gum with a matte sheen. Under long-wave ultra violet light the paper gives a low fluorescent greyish white reaction, with sparse concentrations of low and medium fluorescent fibres visible in the paper, as well as some brown woodpulp fibres. This is what Unitrade lists as the MF paper. The ink colour under UV is black. The width of the selvage suggests that this comes from the upper left pane. Unitrade values a VF-75 NH plate block at $6.50. The block offered here grades VF-84 NH as follows: Margins/centering: 54/70 Paper freshness: 5/5 Colour: 5/5 Impression: 5/5 Absence of visible paper flaws: 5/5 Perforations: 10/10 Note any vertical or horizontal line shown in the scan is the edge of the acetate strip that the stamp was resting inside on the stockcard.

Note: the above scan is a stock photo as are all my scans for material after 1952.The item (s) you will receive has (have) been carefully checked to adhere to the above grading standards, so while it (they) may not be exactly the same, it (they) will be of the same quality. Also, I do not provide back scans of NH stamps or blocks after 1952 unless they are required to illustrate some attribute of the paper or gum.
