Richard ,

I have this same exact chip in my collection .
It is an " authentic casino chip " from the
Allan Boyd Club in Reno, Nevada . Though not
currently listed in TCR8 , I would estimate
the value of the chip as a " K " value of
$60 to $74 . I sold one in the past 3 months
for this amount to a Reno collector whose father
was a dealer at the club and authenticated the
chip as " genuine " . John J.
