Regarding that story about the Canadian notes, it seems like an unnecessary risk to me to go spend the altered $5 bill with the foil. It sounds like you can turn $5 in to $100, and only have to risk getting the $100 in to circulation. Or you can turn $5 in to $105, but then you have to risk getting 2 bills in to circulation. It's significantly more risk for a very tiny increase, no?
