I like to collect odd coins. I mostly have a bunch of the 'special' Canadian & American quarters, which have things other than the caribou/eagle on them. As for other countries' coins, I have one from a middle eastern country(dunno which), and one old French Franc. I actually found the latter in a quarter dispensing machine, XDD. Even before the Euro was introduced in France, this particular coin was worth less than a Canadian quarter, so I guess someone was using them in their place. See, they are pretty much the same size. XD
I also have two old Canadian $5 bills, though I want to get my hands on an old $2 one. ^^
