Coin collection box in a typical National coin piano. The coin collection box is located underneath the "keybed" area shelf and on the right-hand side of the piano case. It and the electric motor share the same compartment. Visible above the black painted coin box is the bottom portion of the shiny sheet metal coin collection chute that funnels any coins passing through the coin switch mechanism into the large and lockable steel coin collector box. The box is comparatively very spacious, more so than the cash collection boxes on most contemporary coin pianos, suggesting an expectation of many nickels flowing into National coin pianos. Inside the top portion of the metal box are a pair of brackets on which to hang the stiffened hoop sewn into the top edge of the suspended cloth bag used for the collection of coins. The cash bag can be quickly pulled out and replaced with an empty bag. This makes collecting and transporting the day’s receipts both quick and easy.
