France, Scott 1024, 25c Gallic Cock from 1963. Scott mentions there was an experimental luminescent variety. Maury has the regular variety as 1331, and lists a scarcer yellow phosphor variety as 1331B. I have a Scott 1024 which fluoresces under UV light. It has been expertized as Sc 1024, "fluoresces white like Canadian HiBrite paper and is not the rare yellow phosphor", but no further catalog numbers are given with the opinion. Maury lists some 18 varieties of the regular stamp but none specify paper variety. Is this a common variant of the regular variety or does it fall into a EFO category? Thanks in advance for any additional information.

(25 c) There are three papers: the ordinary, another white paper, but slightly luminous under the quartz lamp. Then, the good, No. 1331 d (Y. & T.) that is really fluorescent yellow under the quartz lamp.


As for the 30 c. there are two papers, simply a set a little bright but it is neither luminescent nor fluorescent.

Thank you, perf12. Do one of the catalogs assign a separate number for the bright white paper variety? I'm trying to figure out a value relative to the common variety.

Just looking for some opinions on what stamps are luminous. The yellow bottom left for sure. Bottom row middle and right suggest they are also luminous stamps. The second from bottom row appear somewhat luminous and even less with row above hem . Top row is the normal printing for reference. Opinions.
