Discriminator for bimetallic coins

Abstract

A coin discriminator has a coin path along which a coin, containing a first portion and a second portion made of different metals and/or metal alloys, is arranged to pass. An electrical mechanism supplies time-varying drive signals to the coil mechanism. A detection mechanism detects eddy currents induced in the coin by the coil mechanism. The coil mechanism is arranged to induce in the coin an eddy current loop, which in a predetermined region of the coin crosses a bond between the first and the second portions of the coin.
