I can now report the finding of two different papers used to print the 1970 5d Christmas stamp, on comparison one of which appears to be of a non-fluorescent type set against a quite highly fluorescent one that reacts strongly under long wave ultraviolet light.

The fact that these paper differences have been ignored by major catalogues means that many collectors are not aware of such varieties being in existence, a difference in a stamps paper is as important as to the way it was printed and I am sure that some other QE ll issues have also been likewise affected by similar differences.

I have selected 4 used examples of the said stamp (two frontal and two reverse images) in order to exhibit the differential found..........

The type of paper that a stamp has been printed on can make a vast difference regarding its scarcity and value of that particular stamp in question. Neither of the above-mentioned varieties of these stamps are worth much, but the difference is quite obvious when inspected under long wave ultraviolet and adds a new variety for the collector to bear in mind.

An extreme example of a paper variation was that of the Canadian 2c large Queen discovered cancelled in 1870 as depicted by Mr. Christopher McFetridge of Brixton Chrome, a Canadian dealer extracted from his article of studying a stamps paper as follows .............

The complete article based on other paper variations and what to look for can be viewed by going to >>>

A section of the article dedicates itself to variations on the luminosity of fluorescence found with stamp papers when viewed under longwave ultraviolet light and gives a list of intensities based on what is known as the Irwin scale.

Maybe an adaptation could be adopted and used for cataloguing British stamps on a similar basis, as the only differential/discrimination that is used in specialised catalogues for the multiple crown Wilding definitive papers is cream or white(r), which appears to be totally inadequate under the circumstances giving no scope for any of the variations that exist and abound.

Take the following as an example :-

The three stamps above are all currently classified as being printed on a whiter paper just because they were produced after 1962.

It just doesn't make sense !!!!!
