MGM Desert Inn $1 Casino Chip OBS PMSC

Hard to find obsolete chip or cheque from the MGM Desert Inn. Plastic with a molded slug core. I believe this hotel was only under this ownership from 1988 to 1991, so this chip would have come from that time band. Has probably seen table play but is in excellent condition. I'm in the process of thinning out the duplicates from my personal collection of casino chips and tokens that I accumulated when we lived in Nevada. All items in this collection were obtained personally by me, either through actual play or at the casino cage.
