Abstract: A coin acceptor which receives coins in a slanted coin chute with a final size gauge system. The coin is first rebounded against a tapered wall and enters a first zone. All three coin sizes enter the first zone and then the lightest weight one passes down a tapered ramp which is spring loaded, but the lightest weight coins will not depress the ramp and therefore such coins are diverted into a second zone. The heavier different sized coins pass down and trip the tapered ramps, both a first and second one, and then the widest of the coins continues downwardly in the first zone to be processed and sized for diameter. The largest diameter coin is trapped between two pins where it is then tilted off of a ramp onto a diverter and passes into a third zone for processing. As all of the coins reach the bottom of their three separate zones, they enter into a final size gauge system which has three coin chutes sized precisely to reject any coin which is bent, burred, or oversized.
