Here is my contingency plan.
I'm not sure if this exactly fits the theme, but I came across something called "Bank Staff Training Notes". I guess that Chinese banks use them to train their tellers for international travel. I don't know much about these other than I stumbled across them one day in an unrelated search. Figured I'd add them here and maybe these would be valuable. It looks like they are for sale and are marked so that they would not be mistaken for originals.
I have Euros from theim, the printing is very poor quality and there's chinese marking on theim.
