Canada #J31iii (SG#D35b)4c Carmine Red 1973 Centennial Postage Due Ribbed HB Paper UL Block VF-80 NH
A well centered and very fine mint NH upper left inscription block of 4 of the 4c carmine red postage due stamp from the 1973-1977 Third Centennial Postage Due Issue.
Vertical wove paper with no ribbing on the face and white PVA gum with a satin sheen. Under long-wave ultra violet light the paper gives a low fluorescent, bluish white reaction, with a low density concentration of medium fluorescent fibres visible in the paper, across the entire block. This is what Unitrade calls the HB paper, even though there is really no true HB paper on this issue the way that there is on the second issue (8c & 12c) for instance. Unitrade values a VF-75 NH block at $25. The block offered here grades VF-80 NH as follows:
Paper freshness: 5/5
Absence of visible paper flaws: 5/5
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.
