Although I do not collect Mother-of-Pearl gaming chips, I acquired these chips as one of the finest examples of intricate carving found on MOPs.  If anyone can attribute these chips please email me.  I would guess that the chips are French. Possibly Casino d'Montrond-les-Bains

These chips are available for trade for the right offer of crest & seals and/or ivory poker chips.  Again, email me if interested.
