Cory paid $700 (and would have paid $900 if he lost the pill contest) for a set of ivory billiard balls and 1920's through 1950's clay balls, with the cue ball missing (replaced by plastic cue ball). I was surprised he paid that much, given that they low ball everything so much.
"What do we have here... the Holy Grail, complete with a COA from Jesus Christ himself? I can do 50 bucks. There just isn't much of a market for that kind of thing but it sure would look nice in the shop. OK, best I can do is $55, man."
This sale reminds me of a set of turn of the century scrimshawed balls my girlfriend found in an antique shop. I think we paid $45 or $50...did pretty well on that one.
