Trivial Pursuit games seem to be good sellers. I noticed that Amazon had Trivial Pursuit: 6th Edition for $219.99 in the brown box. A quick check on eBay reveals the 6th edition in the red box sells for $10-$55. Link to red box 6th edition sales. This is an item I would put in your eBay store at $60 and use the "make offers" choice if I had a red and of course a brown one would go on Amazon. Other editions have varying prices.
