Canada #J35iii (SG#D39a) 10c Carmine Red 1973 Centennial Postage Due SF LV Paper UL Block VF-80 NH

SKU 222435038320

A very fine mint NH upper left inscription block of 4 of the 10c 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 an eggshell sheen. Under long-wave ultra violet light the paper gives a dull fluorescent, light violet reaction, with sparse concentrations of low, medium and high fluorescent fibers visible in the paper. This gives the strongly speckled medium fluorescent reaction that Unitrade is referring to in their listing, although this paper is smooth, whereas Unitrade's is ribbed. This is therefore an unlisted variant of the strongly speckled paper that Unitrade lists as J35iii. Unitrade values a VF-75 NH block at $75. The block offered here grades VF-80 NH as follows:

Margins/centering: 50/70

Paper freshness: 5/5

Colour: 5/5

Impression: 5/5

Absence of visible paper flaws: 5/5

Perforations: 10/10
