What was the name of the company who made the wafers for Burt Company and, what country were they located in and did they have a catalog...?

Did they manufacture in pre-WWII?

This is a Celluloid-type, Europen-type "5" jeton that is worn and, though I do not know who the manufacturer was, the style appears in at least one distributor's display from way back when.

...and this is the same metal wafer in its original state of preservation with full texture detai

...and this is an example of a "5" from Gran Casino San Sebastian, Spain.

Now, the BIG question; did Burt Company or anyone in the US make a clay composition chip with the same type textured metal wafer seen above... and for whom?

None of what I show above should be confused with metal "overlays" such as in Monaco and other European countries..
