Hey Carol,

The chip from Prairie Knights Casino, Fort Yates, ND (see CG01607 at: http://www.chipguide.com/ndfypk.htm ) and the chip from Speaking Rock, El Paso, TX (see CG00212 at: http://www.chipguide.com/txepsr.htm ) BOTH have their respective casino names on one side.
I made a composite of the respective chips, as shown below.
If your chip has the same text on both sides - then it is either an error chip, or from a new location...

I hope this helps..

Dick

P.S. It was nice meeting you at the trade session - albeit we didn't talk much. Too many good chips to look at!!! See you on ebay! (A.K.A. chipscan on ebay)
