Whenever I travel I always make sure I keep atleast one piece of their currency. I also like to keep foreign currency if I'm lucky enough to find some here. Either way I here's some pics of this cool trackable with some of my collection. There's currency from Australia, Greece, England, Jordan, Italy, Jamaica, Netherlands, Japan, New Zealand, Cuba, Egypt, Tonga, France and a few others that I'm not sure where they are from.
