Q: I’m wondering what my Marx-a-Serve Electric Table Tennis game is worth. I don’t have the original box or instructions, but I have all the game pieces—the battery-operated base unit and nets, four ping-pong balls and two rackets. The base unit shoots out a ball and the player hits the ball back into the net. The ball then falls back into the machine for continued use.
A: Your game, with its original box, sold online recently for $32. Without the box, it would sell for less—perhaps $20 if the mechanism still works.
