It might have more value to someone who wants to add to a collection. Shipping would cost as much or more than the table is actually worth, so unless it's someone local you might be hard pressed getting more for it. If you've got the room and patience, you could just watch the board. People come on here looking for old tables occasionally. I recall someone looking for parts for a Mirco on this board, but I think it was about a year ago.
$50 is not unreasonable. I can't imagine someone paying more than $150 even if it's in top condition. Serious players are going to be looking at a Tornado or Warrior. For that reason, I don't think you'll be able to get much more than $50. Someone looking to just get something for the kids or to rekindle old memories is probably who you're going to sell it to. At $50, it's still cheaper than Wally World and not really a bad table for the non-tournament crowd. If I remember right, it plays similar to a Deutcher Meister. I haven't played on one in over 30 years. The bow tie men give it a unique look.
