ABSTRACT:
A coin sorting apparatus in which the oscillation constants of oscillators change with the passage of a coin, and the amount of change in each of the oscillation constants or a value converted therefrom is compared with a reference value of a coin to be identified which is stored in a memory to identify whether the coin is genuine and the class thereof. Whether the reference values for each coin are corrected is determined by a plurality of counters which correct the reference values of corresponding classes of coins when their counts exceed a predetermined set value. At the same time, when the inserted coin is identified as genuine, a corresponding counter is activated, thus improving the performance of eliminating spurious coins without reducing the acceptability of genuine coins even under ambient temperature changes or secular variations of component elements with time.
