Self-contained coin boxes for nickelodeons, and any other types
of machines you wish to make coin-operated, can be obtained from:

  Coin Mechanisms
  400 Regency Drive
  Glendale Hts, IL  60139

The boxes are made to bolt or screw to the wall or side of the machine.
They make many different models and can custom-make anything you want,
including ones with timers in them.

The last unit I bought some years back cost $83.81 and that included
shipping and COD charges.
