~~~ jurisdictions around the world, especially in France and in Eastern Europe.

In France, we know of several monogrammed (well-known monograms) pearls and plastic that traveled to as many as three different casinos -- and in some cases even if only one letter of a monogrammed piece closely matched another casino's monogram pieces it was set in play if needed.

Further east, in Europe, there are posts here about the Capri chips from Cuba (map graphic) being on the game several years back... reported here by someone in the business at that time.

Known chips from Monaco were used in Northern Europe and on a ship from Japan in the South China Sea... and, of course, our American illegal clubs/games used chips from other locations.

In Puerto Rico, there were pearl chips in denominations of 5, 50, 100 and 500 with a "FC" monogram used at Flamboyan Club on a high-roller game... The "1" from that series is rare.

Interesting hobby we have...

I think the term often used is 'emergency' money...
