This old Florida chip was used at an unlicensed mob casino in the 30s and 40s. TGT mentions Meyer Lansky being connected. The construction involves a thin metal inlay on both sides that was either etched or die-cut. Small Key mold on a 39 mm standard size chip with two white inserts. Condition is Used, EXC. Stands on edge. No damage to the clay edges. Listed in TheChipGuide as CG124458.

I haven't tried to clean the chip or remove the surface tarnish on the inlay but you probably could if desired.
