<p>In apparatus for rejecting from coins or tokens those whose magnetic characteristic exceeds a prescribed threshold, said apparatus comprising a path for the coins having an opening in which a first magnet engages when a magnetic coin passes along the path opposite the opening and, upstream of the first magnet, a second magnet, the improvement that the magnets are carried by an integral mounting and are separate pole pieces and the second magnet is shaped or positioned so that the magnetic force passing in front of it along the path is less than that with which the first magnet is attracted by this same coin when it passes in front of the opening.</p> |
