Below are 12 chips that I would like to know where they were used. They smaller than regular chips and feel like they are made of ceramic. I think they may be from Argentina but I do not know. If you have any information on these, I would like to know what casino(s) they are from and where the casino(s) were located. The chips that only show one side are identical on the back except there are not any initials on the back.

Any help would be greatly appreciated.
