Show Me Yours and I'll Show You Mine

I have multiple two dollar bills. I don't know why, but my local recycling yard uses them (a lot!) to pay customers. I used one in a self checkout at Walmart, just to see what would happen. Machine ate it, just like any other us currency. Frankly, i was surprised.
I also have five CANADIAN two dollar bills, that haven't been issued in decades!

U.S. two dollar is a gorgeous note!. The two-buck canadian....not so much.
