A coin processing system for processing a plurality of coins of mixed denominations comprises a rotatable disc for imparting motion to the plurality of coins, a sensor for differentiating between valid and invalid coins, a stationary sorting head, a diverter and a controller. The stationary sorting head has a lower surface generally parallel to and spaced slightly away from the rotatable disc. The lower surface forms a queuing channel and a plurality of exit channels for sorting and discharging coins of particular denominations. The queuing channel has a first segment for receiving coins and a second segment for moving the coins past the sensor and is configured to move coins at a faster rate along the second segment for increasing the spacing between adjacent coins. The diverter is disposed along the second segment beyond the sensor and is moveable between a first position for permitting coins to proceed to the plurality of exit channels and a second position for diverting coins to a reject region. The controller moves the diverter from the first position to the second position when the sensor detects an invalid coin.
