Could very well be a NJ joint. The chip seen below came from a room in a building named The Floridian Hotel.

I don't know if you have copies of the "Capone Letters" I found years ago when I was doing the Floridian Casino reasearch (nobody knew where the chips were from, prior), but one letter from Michael J. Glenn to Carl G. Fisher; May 29, 1930, states that Capone also tried to muscle in at the Deauville Casino but was refused, and after some sort of a threat, some men were brought from NJ to protect Deauville from Capone's crowd.

Anyway, let's find the chips first and attribute them second.
