The Trocadero was one of several illegal clubs located in what was known as "The Strip" both in Henderson, KY and Evansville, IN. Other clubs were The Dells and Kasey Klub. This info was from the magazine, "USA Confidential." I have had 2 pair of dice from the Trocadero, one dated 1945 and the other 1946. I do not know what kind of chips were used. I DO have some chips from the Kasey Klub, however.
