This set was given by Bill Harrah himself to entertainers that worked his South Shore Room in the 80's. I aquired it from one of them last week.
The 4 chips are incased in a thin lucite or plastic.
It appears as if the case was made with 4 holes in it. Then the chips were laid in the holes and then the holes were plugged. Will consider offers for the set as it is...the chips look like they could be removed with out a lot of trouble. Aloha, Steve
