ABSTRACT:
The selector assembly includes a support plate and a rail that directs a coin into a coin serration detector assembly. The serration detector assembly includes a body pivotally mounted to the support plate, and a coil spring having one end attached to the body, the opposite end being provided by a coil disposed transverse to and engageable with the edge of a coin moving in a predetermined trajectory from the rail. The end coil engages the serrations of a serrated coin to rotate the spring into the path of the serrated coin to change the trajectory and direct the serrated coin in one direction, and engages a substantially non-serrated coin to rotate the spring away from the trajectory and permit movement of the non-serrated coin in another direction.
