You may be right Andy. But, you have strong nitch collection in the Hard Rock area. I doubt there are that many Riveria only colectors. Frankly, unless you are into silicone implants, the cars are prettier chips <G>. There is a little bit of unique history associated with these chips, but it is nothing compared to the Moulin Roughe or Binion's Horsehoe or Stupak's places. I think the feeding frenzy will wear off. In the words of one of the television antique appraisers "Who collects Bicentennial stuff now?"
