These came from the Gene Trimble collection and I assume are original Dave Whalen creations.

I have quite a few of the swirled chips in my collection but don't really collect the solid colors so I thought I would offer them here first.

Full disclosure: these are Re-manufactured chips and not in the original colors made for the casino.
With that being said just about all the ones I have seen are one of a kind and these are most likely the same.

If you have any interest, let me know.

I will also trade for other swirled modified brass cores I dont have (Not solid colors though).
