<p>A coin selection apparatus comprises detection coils and an oscillation circuit which detects changes of impedances of the detection coils caused when a coin pass through the detection coils, as a change of a voltage output. The detection coils include at least two detection coils opposingly arranged to coin paths and one detection coil has coils connected in series and in phase and the other detection coil has coils connected in series and in opposite phases. Those coils are arranged at a spacing smaller than a minimum diameter of a coin to be selected and all of the coils are connected in series and connected as a resonance element of the oscillation circuit. Thus, material, thickness and diameter and other appearance characteristic of the coin are detected based on the voltage output of the oscillation circuit. Accordingly, the coin selection apparatus is of simple construction and has a small number of components.</p>
