Last week I reported on the 37p fluorescent head variety. It surprised me that so many avid Machin collectors had no idea that this existed. Which brings me to another relatively recent variety to your attention.
This is not so dramatic or spectacular as the 37p, but is different to the norm that have been printed before. In order to see this you will need the Recent Harry potter mixed Machin Pane, darkness and a Long wave UV lamp.Check the Maroon 1p stamps in particular and you will discover that the ink fluoresces orange/yellow. As with the other Machins on this pane it has year code M18L/MPIL. As far as I know all 1p stamps from the Harry Potter panes fluoresce in this manner. I have alo heard that the 5p Walsall sheet stamps have a similar appearance, I have not examined them as yet.
New rate 2019 Machin stamps may have coil varieties on official Royal Mail fist day covers and in presentation packs (as in the past). I have not had the opportunity to examine them for direction of print as yet. In fact I have not seen the presentation pack to date. One to check if you have them.
A retail booklet containing two self-adhesive birds of Prey stamps and 4 x 1st class MCIL M19L stamps. will be issued on 04 April 2019. The Machins are not new.

On all 1p Dark maroon and 5p Ash pink values, printed in lithography by Cartor (mainly from prestige books) the ink fluoresces orange/yellow under Long wave UV light.
I have described this feature in Deegam Report No.131 and I have listed there all known examples.

Thanks Hanns,
I have just checked the Norvic Blog and it seems there a are quite a few sheet values that fluoresce in this manner. I will try to compile a list of all varities.
