I have one of the original $5 Hard Rock Casino chips from Biloxi. This was part of the rack that was never used when hurricane Katrina destroyed the property days before they were scheduled to open. This chip has clearly spent some time buried below the sands of the Gulf before being dug up. Since I don't collect $5 chips I'll trade it for any $1 casino chip from the U.S. that I don't already have (see the link below for my webpage). E-mail me if interested or if you have any questions.
