Abstract: A coin mechanism comprises a coin entry point (2) to receive coins (1), a coin exit point (19), a coin acceptor (5) having an inlet (7) for coins to be tested, a sensor and processing arrangement configured determine the acceptability of coins under test that enter the inlet, an coin accept path (10) for acceptable coins and a non-accept path (12) for non-acceptable coins. A first coin conveyor runs along first coin feed path (6) from a coin receiving portion that receives coins from coin entry path (3) to deliver coins in succession to the inlet (7) of the coin acceptor. A second coin conveyor runs along a second coin feed path (17) from a coin receiving portion that receives coins from the non-accept path of the acceptor to the coin, to deliver coins to the coin exit point.
