Question regarding the Jubilee Blue Green issue - I have a range of the Hendon described Black U/V reaction shades but also a small selection of those that under U/V shine bright whist normal are a dull beiges colour. Has anyone a suggestion - I have researched chemiluminescence and luminescence but cannot find a definitive answer - appreciate all suggestions.

Over the last few years I have been studying the various papers found to have been used to produce British stamps during the Elizabethan period but was not aware of Victorian stamp papers concerning with what you have described, is there any chance of exhibiting these anomalies in the form of attachments in order for myself and other collectors to see ?
It does help rather than just text !
