ABSTRACT:
Apparatus to prevent the theft of coins in the coin return channel of pay phones and coin vending machines. Three vanes are pivotally mounted within or adjacent the return channel to provide a bypass path for returned coins so that blocking of the coin return door or the use of a wire attached to a coin for inserting a wad of material will not prevent retrieval by a user of the telephone or vending machine.
