ABSTRACT:
Counterfeit coin sensing apparatus including a transport system for continuously directing a plurality of successive coins along a feed path. A first coin sensor is disposed along the feed path for producing a denomination output signal corresponding to the diameter of each coin, and a second coin sensor is arranged along the path to produce a phase and amplitude displacement output signal corresponding to the metal content of the coin. The output signals from the two sensors are received by an acquisition system which converts the signals into corresponding standardized signals and then directs the standardized signals to an analysis system which compares the denomination and phase and amplitude displacement signals with stored signals representative of valid coins. When the sum of valid coins as represented by the two signals equal the correct fare, the analysis system produces a validation signal which initiates the transfer of each group of received coins into a first coin collector and then into a second coin collector. The coins in the first and second coin collectors may be cross-checked visually before being sent to storage.
