A coin wrapping system comprises (1) a coin wrapping mechanism forming loose coins into wrapped rolls of coins, (2) an operator interface panel, and (3) a controller coupling the operator interface panel to the coin wrapping mechanism. To provide the coin wrapping system with total flexibility in operation and other functions, the operator interface panel includes a display and a touch screen mounted over the display. The controller causes the display to display keys. The controller operably couples the touch screen to the displayed keys such that actuation of the touch screen at a position above one of the displayed keys causes the controller to perform a function associated with that displayed key. Preferably, the controller is operable, via the touch screen, in a plurality of modes including a basic operating mode, a memory recall mode, an adjustment for wrap quality mode, a diagnostics mode, and a programming mode. The basic operating mode preferably includes an error detection and recovery function. The controller causes the display to display keys associated with a selected one of the modes.
