ABSTRACT:
A device for sensing predetermined characteristics of an object such as a coin in order to determine the validity or genuineness of the coin and in some cases also the size and/or denomination of the coin, the device including a combination of optical sensors and an associated electro-magnetic sensors which operate together to expose the coin in different positions to the field produced by the electro-magnetic sensors so that if there are variations in the coin such as variations in the materials from with the coin is made these can be sensed and used to determine the coin's validity.
