A fine mint NH single of the 25c 1977 Silver Jubilee Issue. Comb perf. 12.6 x 12.2. Vertical wove paper with no ribbing or visible mesh. Smooth creamy PVA gum with an eggshell sheen. Under ultraviolet light, the paper appears low fluorescent bluish white, with a sparse concentration of both low and medium fluorescent fibres visible in the paper, as well as a very sparse concentration of high fluorescent fibres. Unitrade lists this stamp as being on LF paper, but this is a gross over-simplification, as the above description shows. There are in fact, at least seven different types of the LF paper. The scarcity of these varieties varies widely, with this being one of the scarcer ones, based on my examination of over 1,000 stamps. Only one block and a few singles were found to be on this paper. Unitrade lists a F-65 NH single of the most common LF paper at $0.50, but I think $1 is a more realistic value, given the scarcity of the paper, and the fact that the DF paper, which is of comparable scarcity lists for $1.25. The stamp offered here grades F-70 NH, as follows: Margins/centering: 40/70 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.
