I finally got some Euro as emergency money for my trip to the Canaries Island and frankly I don't like the bills... the higher value bills are larger so you can't hide them behind lower value one like you do for canadian dollar. someone can guess how much money you have simply by looking at how many bills are bigger then the rest. A weird way to make money secure if you ask me.
I know why they do this tho, blind and disabled will have an easier time using the money. It weird... for a canadian used to one sized bill.
