Those are not a set of ordinary clay chips. They are actually two different chips from two different casinos.

The chip is of a mold which is desirable to many collectors. I don't believe either chip was previously known to collectors which means that none of us have these chips.

As to a price of $1400 -- these chips if sold individually wouyld easily sell for more than this. So a dealer will look to purhase the whole lot and then sell them individually.
