Summary:PROBLEM TO BE SOLVED: To provide a coin identification method and a coin sensor for highly precisely discriminating the quality of a material or the thickness of a coil passing a coin path by an inexpensive circuit configuration. SOLUTION: In a coin sensor 1, an oscillation side coil 4 and a reception side coil 5 are faced to each other with a coin path 3 interposed, and an oscillator 6A is configured of the oscillation side coil 4 and an associating circuit 6 so that the coil 4 is oscillated, and an oscillation signal of the oscillation side coil 4 when the coin passes is received by the reception side coil 5 which is not controlled in an oscillation state with the oscillation side, and the quality of the material of the coin is discriminated from the change of the output signal of the reception side coil 5 when a coin C passes the coin path 3, and the coin C which has passed the coin path 3 is identified based on such discrimination. The output of the oscillation side coil 4 and the sensitivity of the reception side coil 5 are increased, so that it is possible to achieve an inexpensive coin sensor for obtaining the output signal of a level which is sufficient for practical use.
