Abstract: A coin handling apparatus for a coin-operated stamp vending machine. The coin handling apparatus is adjustable to permit operation of the vending machine by a single coin or a plurality of coins. This arrangement permits the machine to be set to dispense items of different monetary values. The adjustment of the apparatus with respect to the number of coins required to vend may be easily made in the field so as to eliminate the necessity of removing the vending machine from its operative location. An arrangement is also provided for locking out a coin when the operating lever is moved too quickly. This insures that an item will be dispensed each time the vending machine is operated.
