Well, here are some foreign bills I inherited along with my last batch of US bills. I haven't done much research on them yet, but some are very nice. I especially like this Brazilian 20 Note. The pattern looks so familiar doesn't it?
The Brazilian note is a 20 Milreis (20,000 Reis) that looks like it has been overprinted '20 Cruzeiros' as a result of Brazil changing over to decimal currency in 1942. The Mexican note is a 1 Peso with 2 handstamps on the back.Some of these are quite scarce,but this particular one is likely to be very common. Aidan.
