Abstract: A coin checking device is provided in a coin handling machine for discriminating genuine coins from counterfeit. The coin checking device includes detection coils comprising a transmitting coil for generating an exciting voltage and a receiving coil for generating an induced voltage. The detection coils detect the passage of each coin and sequentially issue signals. The coin checking device also includes a controller which may be a computer. The controller receives signals from the detection coils and makes calculations on the basis of the values of the signals in accordance with a stored program to obtain a reference value. In the controller, the reference value is then compared with a predetermined acceptable value and the degree of any difference in the value thus obtained determines whether the coin is genuine or counterfeit. The reference value in the controller is constantly renewed on the basis of new signal inputs into the controller.
