Abstract

Abstract A method and apparatus for checking coins during their travel along at least one coin channel of a coin checking device is disclosed which contemplates subjecting each coin to a damping measurement to obtain a first type of information about the coin, and also subjecting the coin to at least a second measuring operation to obtain a second type of information about the coin being checked. The invention further teaches the possibility of performing a still further damping measurement to obtain additional information about the coin different from said first type of information.
