Abstract
The present invention provides a coin-identifying method that is fast and that can reject any counterfeit coin that closely resembles a genuine coin, or a counterfeit coin that has a distribution that partially overlaps into a genuine-coin identification region, without reducing the acceptance ratio of genuine coins. It also provides an inexpensive apparatus that utilizes this method. The method and apparatus of the present invention perform a identification in which a first region is set to define a comparison reference for values measured by a first sensor and a second sensor that detect characteristics of a coin, a second region is set in such a manner as to partially overlap the first region, a preliminary identification is performed using this second region to determine whether the coin is a counterfeit. If the identification result is such that the coin is not determined to be a counterfeit, the first region is then used for further identification.
