Abstract

There are proposed a method and an apparatus for testing coins, in which each coin is guided into a coin channel, the edge of the coin is irradiated and the reflected radiation is detected. The edge of the coin is irradiated and sensed in strip form transversely relative to the coin channel via a slit or the like, in such a way that differences in reflection occurring in the presence of grooves on the edge of the coin and caused by the grooves are obtained in the form of a change signal. <IMAGE>
