Abstract
A tamper resistant coin race is provided which establishes a non-linear coin race or path for the coin to traverse. The structure defining the coin race provides communication from the coin race to the exterior to prevent the locking of the coin race by the insertion of foreign matter. Structures are also provided to further limit the insertion of probes into the coin race.
