The handle is provided with a plurality of elongated openings within which are fitted interchangeable functional or nonfunctional cores. The functional cores are sized to receive coins of predetermined denomination and can be made to accommodate any size coin, even foreign coins. An interchangeable bridge includes downwardly exposed ramps or cams to accept or check coins of predetermined denomination. The interchangeable cores and interchangeable bridge are utilized to quickly and easily adjust to any desired price which can be computed when using from one to five coins.
