A paper currency acceptor which performs a first magnetic test on a first predetermined area of a bill corresponding to an area of a genuine bill printed with magnetic ink to produce a credit signal in response to a genuine bill and to reject a spurious bill not printed with magnetic ink in the first area and which performs a second magnetic test on a second printed area of the bill corresponding to an area of a genuine bill printed with nonmagnetic ink to reject a spurious bill made on a copying apparatus employing magnetic toner particles.
