摘要： The present invention relates to an apparatus for accepting or rejecting a single type of coin, which is designed and constructed only to accept genuine coins of a particular value or denomination, and to reject spurious coins or slugs which may have the same dimensions. In such apparatus is provided a sensing coil (L2) a suitable circuitry to actuate an accept solenoid (L3) to receive a genuine coin in an accept slot (20) and to direct all other non-genuine coins to a reject slot (84). To discriminate between genuine and non-genuine coins two parameters are utilized. The first parameter provides discrimination by means of the current being proportional to voltage drop and the second parameter provides discrimina- . tion by a frequency shift, - both of such discriminations being detectable when the coin passes through the sensing coil (L2).
