Automated currency changing machine (10) accepts twenty dollar bills and dispenses a combination of dollar and non-cash items in exchange. Bill intake module (20) receives a bill and checks its value and authenticity Programmable controller (32) calculates change to be given by change dispensing module (40), according to a pre-determined algorithm. A combination of dollar bills and non-cash items, such as coupons or tokens, is dispensed.Non-cash items have "cash equivalent value" to the customer and a smaller "cost equivalent value" to the business where machine (10) is in use. The combined value of dollar bills and "cash equivalent value" of non-cash items is preferably equal to or greater than the value of bill proffered by customer. The combined value of dollar bills and "cost equivalent value" of non-cash items is preferably less than the value of bill proffered.
