Nate - Since the original chips were usually the original issues in circulation for years just about every collector has them, so prices remained flat. Still $3-$4 per chip for those pre-Katrina chips. Any chips from flooded casinos were washed away. Some may have beed found by collectors on the beach in various states of damage. See TheChipGuide for all of the new racks issued after Katrina. About the only chip of any interest was the speed chips issued when the Isle of Capri re-opened (CG16416). They were in circulation for about 9 months before being removed form the casino and replaced with the back up rack.
