Several years ago these "DRINK COASTERS" which have nothing to do with an actual casino were made in 6-piece sets of different demominations depicting casinos in actual gaming jurisdictions (each casino-named set has different borders and graphics).

These are blank on the reverse... and though large and colorful, they should not be thought to be part of any actual chip inventory.

These are nothing more than novelty "DRINK COASTERS" that were made with actual casino names...

Dom L has a complete set of the MC coasters... and a list of the other casinos are mentioned in an archive post, somewhere.
