ABSTRACT:
A method and apparatus for discriminating coins based on their metal or ferrous content. Coins are transported by a rotary mechanism that stops when a coin is accurately positioned with respect to an adjacent metal sensor. The metal sensor is then activated to provide a measurement signal of the coin in the repeatable stationary position. A plurality of measurements may preferably be taken and averaged to increase the accuracy.
