The Casino Municipale di Sorrento opened in 1922, on May 7 in the Villa Gunderrade. It lasted only 3 months.
After the WWII, in 1946 everything was ready for the great opening of the new Casino, in Villa Battista, but it was stopped by government few hours before, the buffet was already setup it was told.
Same story on April 22, 1974. Achille Lauro, well known businessman, used political influence to open the Casino in Hotel Europa, but the police stopped it the first day.
The last try to open a casino was done in 1977 by Anna de Marinis ceo of Beatrice s.p.a., in the Hotel Miramare, she got a 20 year concession from municipality of Sorrento, she paid 60 millions of Lire for the license, but she was stopped again by police the day before opening, fixed on February 7 1977.

I'm not sure about the chips in this pics, I guess they are from the last try, in 1977 or maybe the 1974. sure they are not from 1946 or 1922.
