<p>A coin acceptor is configured to detect a coin of a given denomination which includes regions that present respective distinctive inductive characteristics, such as a bimetallic coin e.g. the new UK POUND 2.00 coin (8) which has different metallic regions (21, 22). The acceptor has a coin sensing station (4) which includes a sensor coil unit (C3a,b) having a coil face (30) past which the coin (8) passes to form an inductive coupling selectively with substantially only with the outer region (22) of the coin. The area of the coil face (30) is less than 72 mm<2>.</p> |
