Abstract
A coin analyzer system and apparatus that provides a detection circuit for comparing a tested coin with at least two different sample coins. Two different sample coins are located in a magnetic field, and the tested coins pass through another region of the magnetic field. In the event the tested coin does not match either sample coin, a rejecting gate forces the tested coin out of the coin chute in a laterally normal direction and into a rejected coin chute. In the event that the tested coin matches either sample coin, the rejecting gate is opened and the tested coin drops through a substantially vertical accepted coin chute. Credit is not extended the tested coin until the coin passes a confirmation sensor, and the determining circuit may be adjusted to vary the credit value extended to at least one of the sample coins. A lockout circuit rejects and prevents a subsequent coin from being analyzed during the time that the circuit is crediting a prior tested coin with multiple credits.
