Jill; Just returned from my usual weekend in A.C. and caught your post. Jerry Birl is correct regarding the rarity of the dark brown Harrah's roulette. I've not seen one either... although I do have a few other designs from that same series. Nice find. Was hoping that I would find something like that in a few of the roulette Round Robins I have participated in.

The three Harrah's "Instructional" chips are also A.C. issues and are illustrated on page 59 of the 2001 Edition of "Black's Catalog". I'm certain that Russ Diaz can supply you with some additional background information on these chips as he is the one who initially discovered them and supplied me with the photos for my catalog.
