I was just there Monday, Steve...
and picked up one of their black $100 brass-core chips for my collection.
I had been meaning to get one for a while, so when I learned about the change in the Hyatt's casino (they no longer have anything to do with the gaming there anymore) I figured it was only going to be a matter of time before all those brass-cores are replaced with a new rack of chips reflecting the name of the new casino ownership.
Wished I could have added one of their $500 brass-cores to my collection, also, but that will have to wait, for now!
