I think its a display case for 12 inch tall figureines that are too old and delicate for full lighting. See the little arms with claws in the display case portion up top? That's where you put GI Joe's shoulders.
The currency collector is for when people want to hold your figurine and you charge them for the privilege.
i got the thing to go, finally. but i am having a terrible time with the touch screen on this thing going unresponsive and i am quite frustrated by this. changing materials, or putting in new jobs is a pain in the butt playing roulette with the touch screen. sometime the buttons work, but most of the time, nope. power down try again.
