- 摘要：
A method and an apparatus for testing and identifying electrically conductive coins and similar. According to the method, the effect of each coin 1 to be tested and identified on a magnetic field, generated by means of coils 101, 201, is measured and compared with a reference value such that a coin is accepted if the measured value is close enough to the reference value. This reference value is determined on the basis of the effect produced by a preselected reference coin 2 on a reference magnetic field generated by coils 102, 201 having the same magnitude as the measurement magnetic field.
