I will sell this set for $39 shipped, in the US.
What I know of the chips is that Rank Hotels was a hotel chain that changed their name to QUORUM Hotels & Resorts Inc.inc 1994. Same both sides. Like new condition.
Beyond that I don't know much else. There was a box found, 20 chips of each color found in box. (20 sets total). I only have a few left.
Please email me if you have more questions.
