Howdy all, I was wondering if anyone had any insight on a value for a 1972 Chicago coin casino? The game is in very good condition considering its 43 yrs old. The playfield is vibrant and has very little wear. Cabinet is also in very good condition with no paint fade or serious gouging. I've heard its a hard to find game but thinking about letting her go. It plays 100%. No broken or chipped plastics. All bulb sockets work. Back glass has no flaking. Everything works as it should. Any thoughts would be appreciated.
