The present invention propose a method to recognize coins in a coin validation unit comprising a runway for coin passage where is placed at least one inductive sensor in form of a pair of coils between which a coin is going through, to said coils are applied input electric signals which responses represent, after calculation, values proportional respectively to the sensor conductance and to the sensor susceptance, said values are an image of the coin characteristics. <??>This invention describes also the coin validation device able to recognize coins according to the method. <??>The objective is to provide a coin recognition method and device which main features lead to a high reliability, stability, and repeatability with the lowest manufacturing costs. <IMAGE>
