Those stay a mystery. Found multiple documents about the room. Entry fees, etc;
They are great and certainly a great item to have in collection.
Belgium is the small brother of France when you start a collection.
It's a far more realistic collection to have compared to France.

So if anyone wants to start, contact John or me and we will get you going.

Belgium = mother of pearl, bone, cardboard plaques, celluloid, polyethyleen, Caro, Bourgogne et Grasset, RFID- chips, World War 2 chips in Reichsmark, CIC chips, 1 denominations, no snappers so far (except 1 that's a possible but not confirmed one with the CO monogram), silver tokens, regular tokens, silver coins, gold plaques, special chips for the birth of the 2 daughters of a casino manager, specimen tokens, drink chips, entrycards, slotcards, only roulette without a 0, ...
Now you know where my money went,
