There is no chance that these chips are licensed by the 5 stars estates, plus Sheldon Adleson, owner of the Sands, would be the sixth person to issue a license for this set. It would be next to impossible to get all six to agree and accept a payment that could be paid from a $50 selling price. If you are in to this type of chip, best to order now. I think there will be a cease and desist order in short order.
If you have the Foxwoods Sinatra chip, I advise you to hang on to it for awhile.
