The coin feed has a coin feed housing and a pair of stops. Each of the stops is movable between a first limit position traversing the coin chute and a second limit position retracted out of said coin chute. Each stop is mechanically linked to said embossing rolls by a cam and a gear train. The mechanical coin feed is located intermediate the coin chute and advancees only one coin at a time to the embossing rolls each time the embossing rolls are rotated 1/N revolutions.
