The large-capacity coin dispensing apparatus of the present invention is directed to increasing the coin storage capacity of a hopper-type coin dispensing apparatus using a rotary disc to dispense coins one at a time. The coin storage capacity of the hopper-type coin dispensing apparatus is limited by the storage capacity of a hopper used to supply coins to the rotary disc. To increase coin storage capacity, the present invention uses a first tank to supply coins to the rotary disc and a second tank to hold a large supply of coins. As the coins in the first tank are depleted, coins are transported from the second tank to the first tank using a conveyor. The addition of the second tank increases coin storage capacity and reduces the frequency at which coins have to be loaded into the large-capacity coin dispensing apparatus.
