First it is not the Pearl River Casino, it is the Pearl River Resorts. the resort consist of 3 casinos, Silver Star and Golden Moon at Philadelphia/Choctaw and Bok Homa on the Bogue Homa Indian community near Sandersville, MS about 15 miles north od Laurel, MS.
the chips at the Bok Homa are $1 and $2.50 Pearl River Resorts chips with chips from Silver Star for other denominations up to $100, I am told there are $500 and $1000 chips for Pearl River Resorts, too steep for my collection. also for cards collectors Bok Homa now have their own slot card. of note on the $2.50 I believe they are only available at Bok Homa, since Earl Hickey only posted a $1 on chipguide

NOTE to chipguide administrators there is a $500 and $1000 chip at the Scarlet Pearl, maybe some one can get a scan of each for the chipguide.
