This chip - one of the holy grails of chip collecting - will be at the convention for sale. It was actually on the tables at the Flamingo Hotel on December 26, 1946, when Ben Siegel opened the casino.
There are fewer than 8 or 10 of these chips known to exist in undrilled condition; this is one of them.
It will be on display at the Jim Sarra/Steve Piccolo table, and available for sale.
