Other countries money looks fake to us sometimes because it's just way different then ours, but dont let the colors throw you off, they usually have some of the same security features as US bills, watermarks,special ink/paper,texture, metal strips, I am interested in this too, I stayed with a couple kids from other countries this summer and I would ask them to show me their countries money, I was actually thinking of starting a very small collection of foreign bills, just please don't let any of my friends or family find out that I am collecting things again!
