Abstract

Certain properties of a coin (1) are measured while the coin runs down a ramp (2) and passes between a pair of coils (6). Measurements in the form of attenuated signals (A1, A2, A3, Amax) are taken at several positions determined by coin edge sensing means (3, 4, 5) detecting the trailing edge of the coin.
