In the most recent Chip Chat auction (#35 / June 22, 2015), there were 2 Cal's chips in it -- lots # 268 and 269.
According to Doug Saito's narrative, there were 3 Cal's operations by owner Calvin Lombardi.

#1: Cals' Gin Mill - represented by lot #268, a $1 chip:

#2: Cal's Food & Cocktails - no chips in the auction.
I don't know if this one had chips, or used the ones from Cal's Gin Mill.

#3: Cal's Jackpot Club - represented by lot #269, a $1 chip:

I don't know anything other than what Saito wrote about these 3 Cal's operations.
