Abstract
A coin tester includes a coin sensor which outputs a measurement signal which is influenced by the presence of a coin. A memory device stores an impedence model of the coin sensor and the model representing an expected influence of a coin configuration model on the measurement signal. A processor computes and applies acceptance criteria to determine whether the coin falls within a predetermined coin configuration.
