To provide a coin discriminating device which can determine contamination correctly even when the surface of coin transportation passage is contaminated while contamination of both faces of the coin can be detected.

This device is provided with a first and a second module for detecting contamination and unifying as constitutional elements at least an irradiation means which irradiates the coin surfaces with light, a first light receiving means which receives positive reflection light of the light from the coin surfaces, and a second light receiving means which receives scattered reflection light of the light from the coin surfaces.
