Hi Patty,
According to the audit edition of TGT, Math Igler's Casino opened in the 1920's and closed in the 1930's. TGT says "may not have had gaming".

They did have a chip (MIC), and they had a token (we have one somewhere). IF they had gaming, it was hidden....we have a postcard that shows the interior and (to the best of my recollection) it looks like just a "supper club". The back of the card says something like "home of the singing waiters" (or maybe singing waters?).
