ABSTRACT:
A coin detector and counter comprising a coreless oblong transmitter coil and a coreless oblong receiver coil spaced apart on opposite sides of a coin path arranged to cause the entire diameter of each coin to pass between the coils. The maximum peak voltage generated in the receiver coil upon passage of each coin is measured as a determination of the conductance of each coin. By comparing the measured conductance of each coin with the known conductance of coins, each coin is thereby identified and counted.
