I also have the Daish's Shanklin casino jetons supported by this copy of the Isle of Wight Chronicle newspaper dated 17th May 1962 (the newspaper is complete, but I have just scanned the relevant part of the front cover) that has a story about the opening of the casino 2 weeks before the Metropole in Brighton which is usually listed as the first casino in England.

Interesting piece of gaming history.

Enjoy
