Yea, I noticed that.. however I jumped over to the Chip Board, and pulled up the $1 and $5 from the MT casinos, and there actually is a Little Big Horn Casino in MT. The $1 and $5 chips may be a previous version? Not sure, and these (Possibly) could be the newer version... but again I'm not sure. The images on the Little Big Horn Casino - also look like those cheap Chinese type chips as well.

Hmmm.
