The monogram of Gran Casino del Sardinero is new, only 5 years ago; you can see some obsolete chips, jetons and plaques in pesetas in my WEB: http://www.franchips.com/sardiner.htm

From the Circiulo Bellas Artes de Madrid I have found these images of chips and plaques.
The Circulo Bellas de Artes is still open but don't have game tables; you can see the WEB here: http://www.circulobellasartes.com/
