The babies were used by transportation, dairy, newspaper sellers, waitstaff, concessionaires, ice cream vendors, and other businesses where a high volume of change is necessary but a register may not be readily available. Tubes are constructed of nickel plated steel with a tough plastic housing. Rear slide hooks attach easily to a belt for convenient access. These coin changers are set to dispense one coin at a time from any one of the four barrels which hold various coins.
