Good day, I hope you are all well?
I'm currently working on the more modern parts of my GB collection and have 'discovered' stamps with these markings. As a simple example, I have 1st Gold and 2nd Blue "Large" PIP stamps in front of me with the markings - but I'm sure I have also seen the same values without it.
So, is there a list or website anywhere of when iridescent markings were introduced to individual values?

codes were introduced in 2009... they appear on forgeries also.
