ABSTRACT:
A token which cannot be easily counterfeited by inexpensive methods is disclosed, together with a simple token acceptance mechanism which will reject easily-made counterfeit tokens. The token is a disk-shaped object which has two sections along its axis. One section has a notched periphery and the second section has a smooth periphery. The notched section interacts with a pawl in the token acceptance mechanism and the smooth section interacts with an arm. The pawl and arm are interlocked so that only tokens that contain both the notched and the smooth section are accepted. Therefore tokens which are easily made by stamping or by turning on a lathe are not accepted by the mechanism.
