Abstract
A device and procedure for obtaining the mechanical characteristics of coins includes an element onto which coins pass which element is elastically deformable under the weight of the coins. This elastically deformable element has sensors to detect an electric signal corresponding to the deformation of the element from which can be obtained the inherent mechanical characteristics sought after in the coin. From the signals produced by the coin rolling along the aforementioned element, which can be in the form of a beam, the device uses frequency analysis to determine a parameter which is representative of the mechanical elasticity of the coin. This parameter is then compared to various stored data to determine whether or not the coin is authentic.
