Apparatus for checking the validity of coins, the apparatus requiring electrical power for its coin checking operation, and comprising means (4,5,6) defining a coin path, and at least one means (HF1, LF, HF2) for interacting with a coin on the coin path to provide an information signal, characterised by one of said interacting means (HF1) providing an information signal in response to at least the great majority of coin types, circuit means (316, 315) for determining whether the information signals are indicative of an acceptable coin, and detector means (316) operable by the occurrence of the information signal from said one interacting means to initiate the application within the apparatus of power adequate for its coin checking operation, the detector means being adapted to so operate irrespective of whether or not the information signal from said one interacting means is indicative of an acceptable coin, whereby said power application occurs substantially every time a coin passes along the coin path. |
