Dear people of this beautiful forum,
I am now going to ask a question that for most of you is a piece of cake, apple - egg so to speak, produces grinning faces, but I have been struggling with it for a long time now.
Recently I started looking for all my old stuff, including GB, and the various catalogs mention stamps issued with and without phosphorescent bindings.
I thought it was not difficult, I'll grab the Europe stamps from NL, those from 1967, the numbers 882, 883 and 884, 885.
That is nice reference material, but I see no difference under the UV lamps.
Solution found quickly, just buy 2 new sets from an authorized dealer and problem dissolved. However, after buying 2x  (!) new sets, I still have the same problem.
For the sake of completeness, I have 2 UV lamps, 1x from Importa (Money & Stamp Detector ) long wave 366 NM and a Safe Philalux 3, Long wave 366 NM and the short wave 266 NM. the latter should therefore be specific for phosphorus.
In those sets that I have purchased extra, I see a very clear difference with 1 stamp, so I think I have 1 (yes 1) phosphorescent stamp.
om now to make the discussion a bit easier I have added 3 pictures and to this wonderful forum the question : " what am I looking at ...???"
I am really curious..
Many thanks in advance for the effort to take.
Raymond van den Berg

Raymondberg you're looking at a phosphorus seal on the right. it turns yellow.
as far as GB stamps are concerned, they only color up if they are mentioned in green, yellow and blue.
the normal phosphor bands do not color up and you can look through the stamp to view it obliquely with a commercial in the background, then you will see matte bands or middle band or only one band on the right or left.

Dear Aartinge, thank you very much for this information. I can continue with this, will also go to the stamp dealer and say that he only sold me phosphorescent stamps..

And here's my next question, which might be a bit more high school, ironed paper. On LD there is a piece of text and explanation about coated paper and the difference with normal paper. The children's stamps from 1960 are given as an example, only I see no difference between the stamps with the best will in the world. Flashing light is of no use to me. I'm definitely doing something wrong. But I would really like to have exact info for the following reason. I am in possession of the 1st editions (1912 - 1915)  of the stamps of Liechtenstein, which are known in 2 variants, namely with coated (couché) paper and with matte (normal) paper. (1917 - 1918). The difference in value is huge, ranging from €160 to €7.
Who can tell me more about this?
Sincerely.
Raymond van den Berg

Raymondberg look again like the phosphor bands of GB commercial behind it and put the stamps on top of each other, you will see that coated paper is smooth and plain paper is clearly matte.
never make too much work of it, just a matter of have a look.

Raymondberg it took me some effort too, but once you've seen it it's (usually) easier the next time.
