Abrégé

A system for verifying authenticity of precious metal coins and bars includes a sensor system defining a sample region configured to receive a precious metal coin or bar therein; a sample support; and a data processor configured to communicate with the sensor system so as to receive a detection signal therefrom and to provide an output signal. The system includes a data storage device and an output display. The sensor system detects a bulk electrical property of the coin or bar. The data processor processes the detection signal and retrieves a stored physical property from the data storage device to provide an output signal that includes at least a measured value of the bulk electrical property and a corresponding range of expected values. The output display uses the output signal to display information for a user to be able to make an authenticity verification of the coin or bar.

Abrégé

According to some embodiments of the present invention, a system for detecting counterfeit or altered coins or bullion includes a sensor system, an alternating current (AC) power supply electrically connected to the sensor system, a detection system electrically connected to the sensor system and the AC power supply, and a data processor configured to communicate with the detection system. The sensor system comprises an impedance component and a measurement circuit. The detection system is configured to determine a calibration complex impedance and a sample complex impedance. The data processor is configured to receive the calibration complex impedance and the sample complex impedance from the detection system, and provide information regarding a composition of the sample to distinguish valid coins and bullion from at least one of counterfeit or altered coins and bullion.
