First off - thanks for the photo.
Information received from a manufacturer is about as good as it gets. What you say did happen but not to an extent to make ineffective the basic records.
This arguement generally finds its way into the discussion when all else fails. In this particular instance there is no evidence to link the owner of the club in Fallon with the owner of the club in California or vice versa.
5 cent chips, I believe there may be six (my guess from memory) for the state of Nevada. Artichoke Joe in Carson City has/had a few - but it is not a common denom for Nevada casinos.
The Esquire Club in Fallon had no other denom in either the large or small crown mold. It is not that unusal, but with such a small denom one would think there would be some others.
It doesn't fit the time frame for Fallon. Just my opinion. Best, Jim
