I agree with Rich that console machines are not worth as much as table models (whose values have fallen also). I don't know if $500 is fair or not. You can probably get new reproduction glass for the machine pretty reasonable but if it needs parts rechromed that can run up the bill fast. Here is my Jennings Challenger Tic Tac Toe machine. It also is a two different denomination coin machine and I had to remove the badly torn fake wood "wallpaper" around the body and refinished the wood. I also replaced the top glass but kept the bottom one since it was in decent shape. If you want to keep it for yourself I would get it but to resell may be a challenge.
