A coin collection apparatus for use with self-service car washing equipment includes a coin meter located in each of one or more car wash bays, a coin collection box located remote therefrom which is inaccessible to the public, and a vacuum providing device remote from both the coin meters and the coin collection box. A conduit extends generally between each of the coin meters and collection box. A vacuum supply intersects each of these conduits along the mid-section of the conduit between the coin meter and the coin collection box. A pump motor is remote from the coin meter, coin collection box, and conduit therebetween, and applies a vacuum to the vacuum supply for conveying coins deposited in the meter toward the collection box. The vacuum supply intersects the conduit at such an acute angle that, although the air is suctioned toward the pump motor, the coins continue along the path of the conduit as the coins cannot make the acute turn. A deceleration means such as a rubber coating, jog, bend and/or elbow in the conduit just downstream from the vacuum supply intersection serves to decelerate the coins and cause the coins to fall downward into a check valve which is momentarily opened by the coin weight to allow the coin to pass into the coin collection box. A switch integrated with the coin meter activates the vacuum upon insertion of the first coin.
