I have those 3 chips in my other post going to the Slovenia address per chipco records.
The plaque and other chips (which I do not have) went to Moscow.
Surely they were not interchangeable? I would not have thought they were denominated in $$.

That said, Casino's Austria and Cherry used the same chips in many locations, and I can see your 2 plastic plaques being used in multiple Split locations also.

Your top left plaque is nice. I bet Doug Smith emails you when he sees it
