Here's a link to PamWest's site on
UK banknote fairs. You could contact her or look over the sight (good stuff on Scottish banknotes) & then check out the
IBNS to see if there are any contacts there (who could possibly point you in the right direction). I realize that the links are for banknotes but I'm sure that someone would probably know what's up for UK/European coin collectors too. Good luck!
