A coin collection and analyzation apparatus has a coin track extending between a coin opening and an escrow relay which escrows coins and then diverts them either to a collection box or to a customer return. The coins are analyzed while passing along the coin track to provide an output for operating the escrow relay for determining whether the coin is acceptable or is to be rejected.
