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. If there is such a combination, it allows the vend. A method of the change making system is also disclosed.
