Unless I missed it, The Chip Rack doesn't list this chip at all, and the Campiglia-Wells book lists it in mustard color only, not black, as an R-10 with a value of 75-110-150.

It's probably from the 1950s, when LaVere Redfield was doing a lot of gambling in Reno. I think it's possible this was one of his chips at the Nugget, since he also had his own chips at the Nevada Club.

I had seen the mustard "LR" before but never the black. Does anyone have a good idea on the likelihood of this being another Redfield chip?
