Unlike many of the other lower values of this series of multiple crown watermarked stamps, the phosphor version of the 1/6d Wilding stamp was not released until the 12th of December 1966, having 9½mm violet phosphor bands that consisted of the band on either side of the stamp.

This value was the highest of the small format series of stamps originally issued with denominations from ½d to 1/6d all of which were printed by Harrison and sons, the stamp itself only had a relatively short life as it was soon to be replaced by the 1/6d Machin design on the 8th of August 1967, a period of approximately 10 months with later availability being made from the philatelic bureau for a set time.

The stamps were valid for postal use up until the changeover to decimal currency on the 15th of February 1971, it's possible that a few slipped through the net but you are not going to find many or any for that matter which have been cancelled after this date.

Due to their face value and usage combined with their relatively short lifespan the amount of printings of this stamp would have been relatively low when compared with the previous plain version that had been available since the 16th of December 1958 and the letter rated lower values.

It would be interesting to find out just how many was sold for use in comparison to its predecessor, as the SG specialised catalogue does not seem to have indicated this fact, surely some records must have been kept , does anyone know ?

As with the other values printed after 1962 they were designated as being printed on a whiter paper, but my findings indicate that this was not the case, as the whiter paper tends to go into the realm of both cream and fluorescent specimens.

Here's a view in relation to that fact concerning a whiter paper and an oxidised cream (translucent) one. >

I am sure that you will agree with my findings after seeing the above attachments, as the difference between the two types of paper are quite distinct and easily identifiable.

Should there be anyone with something constructive to report on this subject then please give details, or is silence still absolute ?
Thank you WM.

Another Discovery I recently made concerning variations of paper used to print stamps has been that of the 1/6d regional for Scotland on watermarked paper, first issued on the 1st of march 1967, with what appears to be whiter and cream type paper being used.
This can be observed in the following attachment as seen below >

The specialised catalogue does not categorise any variations of paper being used to print this stamp, yet, there is a difference as you can see.

Here are 3 different papers used to print the 1'6d multiple crown phosphor stamps, as seen under longwave ultraviolet light.

Can you see a difference ?

Some of the paper used to print this particular value was also affected with fluorescent particles when the paper was manufactured.

Here is an example showing a block of 4 of the whiter paper containing the said contaminants, taken under longwave ultraviolet, then filtered to mono.................

There is a file at The Postal Museum which gives the numbers issued on a periodic basis for all pre decimal issues.

I fail to see what that information would accomplish Lennox, as it would only be records of standard issues at best.

Do you have a link to the file in question ?

Thanks WM.

You said “It would be interesting to find out just how many was sold for use in comparison to its predecessor.”

I am aware of precisely the information contained in the files as I have taken images.

It would be possible to have a fair idea of the numbers issued by a combination of statistics from various files.

The total number of sheets printed for this value is already known. This information is already on the website.

It would seem that having this information and not sharing it with others, is what you appear to have in mind !

Have a nice day, Lennox.
