ABSTRACT:
An apparatus for sensing coins is disclosed which is capable of distinguishing between valid and non-valid coins as well as between the different denominations of coins. The apparatus is useful for application in coin-operated parking meters as well as other coin-operated machines. The apparatus makes use of a twin-coil sensor which enables it to distinguish between small coins with high metal content and large coins with low metal content.
