Hi DL20K. Thank you for your reply. Did you have the same experience with the changing colour due to prolonged exposure to sunlight?
I have had a lot experiences with discoloration (as any other collector of stamps and banknotes, and coins, of course)... but, this is a pretty nice shade of blue colour... almost exact as the 20 Mark currency from that period has.
I really don't think that it could be caused by any enviornments...
However, I will be glad to hear is someone has had the same expierence already?
