American money has no iron coinage that I am aware of. Most American currency is either cupronickel or zinc. Even if some foreign currency does, I can't imagine any amount high enough to be found regularly enough to be a useful thing for making nails.You can be forgiven for not knowing this, since from the flag on your profile picture, it seems that you come from a place where coinage actually is made of things that really have value. I mean no offense but I'm dyin' here That's the British flag, they consist of England Scotland Wales and Northern Ireland, First world countries whose money also consists of zinc copper and nickel.
