A memory has stored therein, for each of a number of coin availabilities, a plurality of coin combinations equalling various amounts of change. A microprocessor determines the amount of change due the customer and retrieves from memory a coin combination, if any, stored therein which corresponds to the amount of change due and the particular availability of coins in the change tubes.
