As to why the firm of Stanley Gibbons have ignored the contaminated papers used to print these British Wilding stamps and treated them as "a never was" is a complete mystery, especially when the contamination has been known of for many years by the experts at the Royal Philatelic Society in London.


One can hardly miss such an abnormality !

So why have they been hidden/withheld by SG from being listed for all these years ?


10/05/2021 09:33:45

It can be seen from the various examples of stamps shown to be printed on contaminated paper that they should be classified as being abnormal under the circumstances as against other types of paper produced around that time, and they are definitely a first in the history of British stamp papers when it comes to contamination.

Having looked at the guide relating to various paper variations, I must now come back to the multiple crown Wildings and the contaminated papers.



05/05/2021 19:53:30

As with the previous Wilding issues, these paper variations have been ignored by the majority of catalogues and it means that collectors have not been made aware of their existence, as the difference in the type of paper that a stamp has been printed on can make a vast difference in its scarcity and value as a collectible.

An extreme example of a paper variation being that of the Canadian 2c Large Queen discovered cancelled in 1870 as depicted by Mr Christopher McFetridge of Brixton Chrome (a Canadian dealer) taken from his article 'a study of a stamps paper'.

I have come across another commemorative that appears to have been printed on two different types of paper as can be seen of the 1970 5d (one of the last 3 pre-decimal Christmas stamps to be issued).


Although in used condition, the difference is quite striking when comparing the two types of paper used to print this stamp on its 51st anniversary. Fred.

Based on various findings, it's quite possible that some collectors who have purchased the cream paper versions may have inadvertently been sold an oxidized cream one by mistake, as the majority of the original cream papers are more opaque and not as translucent as the oxidized papers from the printings from around 1964 onwards.

Nevertheless, the oxidized cream papers in some instances could be much scarcer than some of the original cream ones. Fred.

Good morning Gillian, Paul was just giving a reason as to why the sellotaped stamp could be part of a collection, but in his particular case it was a case of mistaken identity with the colour of a stamp used .

As previously stated I normally bin sellotaped stamps, but sellotape is removable from stamps with a little effort and know-how. You could classify it as restoration !


18/04/2021 15:58:06

On further inspection, another thing that has been noted to be different has been that the lighter coloured stamp appears to have been guillotined on the top perforations indicating that it comes from a booklet.


I would have thought a stamp that is so distinct in its colouration and value tablet format would have been separately listed in any specialised catalogue : Is it listed ? Fred.

Thanks for your additional explanation regarding the postage due aspect Paul, it's just that your previous reply was a bit vague to understand : definitely a keeper in combination with the PD !


08/04/2021 07:08:28

You mentioned this fact at the end of February Paul !

What do you mean by a sellotaped stamp being a keeper ?

I normally bin them.


07/04/2021 10:45:25

That's up to you Gillian, a similar substance to sellotape is to be found on self adhesive stamps and these can be removed from the packaging with a little practice by the use of petroleum spirit, but can run the risk of some inks being fugitive along with breathing in the vapours and creating a fire risk.

Your call, Fred.

I have decided to include three positional indicators in the form of coloured arrows been inserted in order to show you the differences found.

It was recorded back in 1983 that some denominations was narrowed to accommodate the queen's profile, but the 14p was not one of them.


The red arrow indicates the large pearl of the necklace in comparison to the upper section of the letter "P" of the value.

The green arrow indicates the white curve opposed to the base of the letter "P"

The blue arrow points to the joining of the dress near the base of the portrait.

There is a positional difference between the two stamps on all three indicators.

Never a truer word said.

You may well laugh Andrew, I think that the majority of collectors of GB stamps now realise that these so-called commemoratives are just a gimmick in order to create revenue for the Royal Mail.

There was a time when collectors used to look forward to a new commemorative being issued, but that was back in the late 50s when one set per year was the norm, but this is no longer the case as every month a new one pops up, the latest one being the mythical King Arthur drawing Excalibur from the stone at a price of £12-75 a set.

Didn't we have an Arthurian legend set back in 1985 at a price of £1-04 ¿?


Many collectors will be saying "oh no ! Not again, this is all getting a bit too much". Fred.

I decided to overlay and align the frame of stamps b&c and do a close up shot of the 2 stamps for comparison, not only are they of a different colour but the value tablet appears to be lower and closer on stamp (b) than stamp (c) in association with the point of the bust as can be seen in the attachment below.


Please feel free to comment on this particular topic, as to what you have noticed that is different, thanks Fred.

04/04/2021 14:53:05

Over the years a collector has a tendancy to hoard philatelic material with the intention of eventually " getting around to sorting them out ".

This latest discovery is one of those moments after sorting through a used mixture I had put to one side several years ago, in this particular instance it concerns the 14p phosphor coated paper in used condition with what appears to be variation of the ink used to print them.

The first attachment is as seen under normal light that gives several different shades to be found .......


The second one is of the same stamps but under longwave ultraviolet .....


Again showing the different shades which compares with the visible spectrum results.

Has anyone else noticed these variations and are any of these varieties listed ?

The oxidised cream and fluorescent papers of the 4d value : Contaminated problem solved ?


By solving one problem they created two additional types of paper that are not listed. Fred.

A previous attachment concerning a Machin stamp appeared to have been printed on a contaminated paper in a similar way to some of the Wilding stamps, which can only be observed with the use of a long wave ultraviolet light.

Here is a further trilogy concerning a specimen stamp that appears to have been printed on contaminated paper that I recently discovered, the stamps in question being 2 X 22p flame red PCP (AOP.) Giving three different views of the same stamps for comparison........



With the reversed view showing the contaminated paper ...........


One can only compare like with like in order to assess the differences. Fred.

The reason for the production of the post 1962 oxidised cream and fluorescent papers was instigated due to the fact that contaminants had been discovered in the some of the stamp papers produced from around 1964.


Two methods was implemented in order to alleviate the problem encountered, one procedure used was the use of a chemical oxidation process to remove them, the other method being the addition of optical brightening agents in which to obscure them, but in doing so two new types of paper was created, giving a total of 3 unlisted papers in the specialised catalogues.

Contaminated, oxidised creams and fluorescent papers, all of which can be found in this topic of "CREAM Vs WHITE". Fred.

Thread: Can you help me identify this stamp
09/03/2021 18:40:02

Good evening Kirsty,

The stamp in question comes from a set of Christmas stamps issued in 1983 and was the lower value of a set of 5.

12½p, 16p, 20½p, 28p and 31p.

Your nan possibly kept it after a postal rate change rather than throw it away, as in 1983 this was the price for a 2nd class stamp, the price currently being 66p.

It's probably worth more as a memento rather than anything else. Fred.

On inspecting many of these 9d phosphor stamps, l discovered that they can be found on two distinct types of paper from which they were printed.

I was unable to find any contaminated nor fluorescent papers with these 9d's and discovered that the oxidised cream variation to be much more prolific than the whiter paper variety being the one currently listed in the specialised catalogue, making the whiter paper more elusive than the oxidized cream paper version.

Here are two attachments depicting both the cream and whiter papers to be found as seen under long wave ultraviolet light.



Good hunting ! I hope you find some of those more elusive papers. Fred.
