A reduced-size coin sorter for sorting coins of mixed diameters is set forth. The sorter includes a coin-driving member and a coin-guiding member. The lower surface of the coin-guiding member forms a plurality of exit channels for guiding coins of different diameters to different exit stations along the periphery of the coin-guiding member. The coin sorter includes an integral base member which concentrically and circumferentially mounts both the rotatable disc and the sorting head. The unitary base member also provides a mounting structure for the electronics and the motor.
