I believe we should add a note explaining these chips further so people can learn from what has been uncovered.

"COUNTERFEIT" ?

"FANTASY" ?

Knowing what information has been gathered...

I would describe the chips as "Hybrid Counterfeits" likely made at the Burt Company. The Chips are presumed to be manufactured by combining
leftover obsolete stock inlays pressed into a newer casino house mold.

Does this make sense?
