A coin discrimination apparatus is provided, which is capable of discriminating the denomination and authenticity of coins accurately even if they are bimetallic coins. A first coin detection sensor, located near a guide, obtains a physical characteristic about a peripheral part of a coin moved on a carrying path. A second coin detection sensor, located apart from the guide, obtains a physical characteristic about a central part of the coin. A third coin detection sensor, located on a downstream side of the carrying path with respect to the first sensor and near the guide, obtains a physical characteristic about the peripheral part of the coin. A fourth coin detection sensor, located on the downstream side of the carrying path with respect to the second sensor and apart from the guide, obtains a physical characteristic about the central part of the coin. An additional physical characteristic about the peripheral part of the coin is obtained by cooperation of the second and third sensors when the coin reaches the third sensor. |
