SG 281 1d Carmine F M7 (7) in very fine and fresh very lightly mounted mint condition with faintest of hints of previous mounting set lower centre.

This the technically Hendon listed fluorescent inked issue of the more recently introduced specialised listing that doesn't actually consider or investigate such inks on Edwardian issues.

This one has a particularly strong reaction and Hendon list this variation with over a 50% premium but in my extensive experience of these and similar issues the occurrence of the shade is no scarcer than finding examples with non fluorescent inks though a hugely different scenario on Harrison P 14 issue.

We of course have a very similar situation with the 5/- De La Rue issue I often warn about not paying premiums for yet will continue to exist until Gibbons relent and acknowledge what is so obvious to anyone using a long wave UV light.
