Not a Nevada expert (!) but perhaps KMH could answer that. Only diff in description is Nevada Club Reno/Crystal Bay is listed with OR-White inlay (Oversized Round) whilst the Nevada Lodge is listed R-White (Round). I am not aware of any difference in the actual chip inlays myself and always thought there was only one version of this chip. I wonder if the different interpretation of color and inlay description amongst the three authors led to this being listed twice in the 18,017 chips contained in TCR #9? If this is one and the same chip that should relieve the burden by one in future editions!
