Canada #456xx (SG#581) 3c Dull Reddish Purple Centennial Precancel 2 Different Papers F-70 NH
Two fine mint NH singles of the 3c dull reddish purple precancelled combine & oil rig stamp from the 1967-1973 Centennial Issue, each on a different paper:
Vertical wove paper with no visible mesh, and streaky creamy dextrose gum with a semi-gloss sheen. Under long-wave ultra violet light the paper gives two different reactions as follows:
- dull fluorescent greyish white reaction with no fluorescent fibres visible in the paper.
- low fluorescent bluish white reaction with sparse concentrations of both low and medium fluorescent fibres visible in the paper.
The ink colour of both stamps under UV is dark purple. Unitrade values two F-65 NH singles at $0.75. The stamps offered here grade F-70 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.
