Abstract
A coin selector assembly includes a coin passageway having at least a pair of thickness sensor unit operatively positioned along the coin passageway to provide respective measurements of the thickness of the coin. A comparing unit compares the respective thickness signals with corresponding stored standard values representative of a genuine coin to determine the authenticity of the coin. Additional sensor unit can be positioned along the coin passageway and excited with different frequencies. Thus, a material sensor unit and a diameter sensor unit or a pair of diameter sensor unit can also be utilized.
