A coin sorter apparatus is provided for sorting coins by denomination using coin thickness as the discriminating parameter. The apparatus comprises a rotating disk located proximate a stationary disk. The rotational movement of coins on the rotating disk carries them into the region between the two proximate disks. Wherein a first selected are of ridges and recesses on the stationary disk surface manipulates the radial position of at least one denomination of the coins to a predetermined radial position using thickness as the discriminating parameter. A second selected area of ridges and recesses of the stationary disk receives the rotating coins carried on the rotating disk after the foregoing radial manipulation by the first selected area and radially releases rotating coins located at the predetermined radial position, thus allowing the coins to exit the region between the two disks at a particular location along the periphery of the stationary disk. Accordingly, all the coins of the one denomination whose radial position was manipulated to the predetermined radial position will be exited from the two proximate disks at the same particular location, thereby successfully sorting that coin denomination from the mixed denomination collection. Each denomination of coin having a distinguishing thickness can be similarly manipulated to distinct predetermined radial positions so that a plurality of denominations can be sorted by the stationary and rotating disk.
