agio (AJ-ee-oh) - n., a fee charged for exchanging currencies.
There's a couple different technical shadings of the term ("The premium or percentage on a better sort of money when it is given in exchange for an inferior sort") but I'm not sure it's worth untangling unless you are deeply into this sort of thing -- in which case, you'd be be able to explain how I'd mangled things. Adopted around 1680 from Italian aggio, exchange or premium, from Medieval Greek allágion, from Ancient Greek allágē, change/barter.
