Abstract: A coin discrimination device which provides for positive transport of coins past a sensor is provided. In one embodiment, a rotating disk, slightly inclined to the vertical, includes a plurality of pockets for receiving coins from a hopper bowl. The disk and bowl are configured to efficiently load the pockets with no more than one coin per pocket. As the disk rotates, the coins, which are thus registered in a desired location in the pockets, are transported by the rotating disk past a sensor. When, based on the sensor data, the item in a pocket is recognized as an acceptable coin, a controllable ramp is lowered to divert the coin out of the pocket and into a path to place the coin in an acceptance bin or bag.
