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 particular stamps are worth much, but the difference is quite obvious when inspected under long wave ultraviolet light 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, this is an extract from his article of studying a stamps paper, and is as follows. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The complete article based on other paper variations and what to look for can be viewed by going to >>>
https://brixtonchrome.com/pages/how-to- ... amps-paper

A section of the article dedicates itself to variations on the luminosity of fluorescence found within different stamp papers when viewed under longwave ultraviolet light, and gives a list of intensities based on what is known as the Irwin scale in order to differentiate the various types of paper used in the printing of stamps, to be found in the table below.

Mr Frank Walton RDP FRPSL recently submitted an attachment showing quite a variety of papers that he had found whilst studying the multiple crown 3d value under long wave ultraviolet, however, none of the higher fluorescent or contaminated papers was exhibited in his collage, this alone gives rise of the need for change !

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

Take the following 3 stamps as an example :-

The stamps depicted above are all currently classified in the SG specialised catalogue as being printed on a whiter paper simply because they were produced after 1962, irrespective of their colour, it's quite obvious that they are not the same and therefore should not be described as such.

I am sure that a device (indicator) could be produced whereby when radiated with a long wave ultraviolet light it would show all the variations given on the Irwin scale, and the stamp to be identified could be placed alongside for comparison, in a similar way that Stanley Gibbons produced the "INSTANTA" gauge to identify perforations : It's hardly rocket science is it ?

The description given of the 10d stamps below is specified in the notes by the SG specialised catalogue in that they were only printed solely on a whiter paper since the change-over date, obviously this is not the case, as one is on a cream paper with the other being printed on a highly fluorescent version, it's quite obvious there is no comparison between the two types of paper that they were printed on, yet are both listed and classified as being printed on the same whiter paper !

Admittedly there are some 10d values that have been printed on a whiter paper, but in total I have found three variations that co-exist.

A similar principal applies with the 4d plain definitive found in booklets first issued 16⁸/65 in which two distinct papers has been noted.

Therefore does SG's definition comply with the original trades description act of 1968 by discriminating against the other two types of paper used to print the multiple crown Wildings post 1962 ?

It just doesn't make sense !!!!! DOES IT TO YOU ?

AND THEN OF COURSE THERE'S THE CONTAMINATED PAPERS TO CONTEND WITH.
