These are the only three pieces I know of on the cover and what design I see in the corners of both rectangular plaques are on one side of the red chip and the high-releif coins on both my chips have the same style lettering and embelisnment on the reverse (denomination) side. I'd say both of my chips were made by the same company.

I have not seen either of the Spanisn casino chip catalogs from Spain to know if this series is in either publication or, if they are, is there any mention of the manufacturer... though, the images on the cover and my two chips appear to be a pretty close match.
