Heres an interesting and fun idea. Of the couple of hundred dollars I received via an online currency shop, one of the single dollars was stamped with a website; http://www.wheresgeorge.com
The concept allows visitors to see where that money has gone around the world. Fascinating to see the same dollar travel further than I ever will!
I’m pleased to say my George may have come to the UK, but he was spent in Hanoi, Vietnam.
