Check the archives by typing in the name Rene Nezhoda or Rene's Law. Rene had some connections with a few North Las Vegas Casinos who produced many "POGS" with mintages of less than 25 - 50. The Mahoney’s Silver Nugget Mike Tyson $100 Chip was limited to 15.
It is my understanding that Rene would then by all of the low mintage chips then control the market.
I'm almost certain that none of the chip dealers on this board would pull a stunt like that.
