Abstract A coin discriminating apparatus includes a light source, a reflected light sensor, light emitting elements, a sensor for photoelectrically receiving light emitted from the light emitting elements and reflected by the one surface of the coin and producing image pattern data of the one surface of the coin, a memory for storing reference data, a first denomination discriminator for tentatively determining the denomination of the coin, a second denomination discriminator for finally determining the denomination of the coin, and a received light amount controller. According to the thus constituted coin discriminating apparatus, it is possible to discriminate whether or not coins are acceptable and the denominations of coins with high accuracy by optically detecting the surface patterns of coins.
