Mel Jung said that they were medallions and that 18,000 were sold in the first year at the cafe. HR decided not to order more because they were a slow mover (that's their excuse). I was wrong in spreading inaccurate information that the gaming commission was involved. They were never intended for gaming but sold in the gift shop and are the same size as conventional chips. I have no idea with that many out there and the fact that they are medallions and NOT gaming checques, why are they soooo expensive? I guess if someone wants to buy them at that price. Not me. I would pay... up to $30 each. They originally sold for $12.
Hope this clears up some of the mystery surrounding these brass core medallions.
