Abstract

A coin discriminating device has first and second coils (10, 20) positioned to induce and detect eddy currents in an outer ring (40) and an inner disk (50), respectively, of a bimetallic coin (30). A storage device is adapted to store coin reference data, and a logic device is adapted to determine an identity of the coin by comparing the coin reference data to data obtained from the detected eddy currents and related to the conductivity of the coin. A magnetic sensor (60) is coupled to the logic device and is positioned to detect a magnetic field generated by at least one of the first and second coils (10, 20), when the coin (30) is positioned betwwen the first and second coils and the magnetic sensor. The logic device uses data obtained by the magnetic sensor and related to the permeability of the coin when determining the identity of the coin (30).
