How the Gold Mech coin acceptor checks a coin
The Gold Mech acceptor (12-4150-01) sorts coins by diameter, thickness, weight, metal content and bounce, and also does a rim test on magnetic coins such as nickel or steel. A coin that is too thick cannot pass between the magnet and the back plate and is wiped out when the reject lever is pressed. Undersize coins drop between the cradle legs, and light coins fail to tip the cradle.
