Thanks for sharing Steve!! Reminded me of my 4807 Club set from Cicero, IL. If these chips could talk... I'd love to hear the stories they had. Some of the things talked about during play or what the owners must have been talking about at the time would be so awesome to listen in on.

There was an article written by John J. Binder, titled "A Batch of Illegal Chips from Cicero", where he talks about these illegal clubs in the Cicero area. For the 4807 Club he states, "The Taylor records which are now publicly available confirm these conclusions beyond any possible doubt. Slightly more than twelve thousand of the “J&J” chips were ordered from 1959 to 1960. The record shows the order was placed by Johnny Varlos, for the 4807 Club, also called the Rock Garden on the card. The same information is on the record card for the “JV” stamped chips, of which over 12,500 were ordered in a variety of colors between 1952 and 1957. A single order for 2020 of the “JVT” chips was placed for the Rock Garden/4807 Club (with no mention of Varlos’s name on the record) in July 1957. John Varlas (or Varlos) and Joseph Vaccaro (aka Joseph Vacco or James Vaccaro), were often arrested as the “keepers” (operators) of 4807 or the sister location at 4730 W. Cermak explains the “J&J” stamp on the chip already linked to the 4807 Club by the Taylor & Co. records. It represents the first initials of these two individuals. It is possible that Vaccaro ran the handbook operation, taking the bets on the horses, while Varlas managed the card and other games. This information also links the chip stamped “JV” with the 4807 Cermak address. “JV” is simply the first and last initials of Varlas (most likely, given his later stature in the Outfit) or/and Vaccaro."

There's some more information in the article if anyone would like to read more into it, but I think its so unique and cool.
