you're $crewed and will either have to forfeit your pennies or face arrest and/or fines as that is a violation. all currency (or currency equivalent [i.e drafts, cashier's checks, travelers' cheques and/or foreign currency in excess of $10,000 u.s.]) must be declared if you are entering or exiting the u.s. that is the law but the tsa "just doesn't quite get it"....
