My wife went shopping at an antique store today and she said she found me some chips. They were great chips! Unfortunately, they are encased in Lucite - why would someone do that to such great chips? Campiglia and Wells' book says that there are only three known examples of the Sahara chip - two in Lucite and one notched. Have some more of them been found or does this make a forth? The Harrah's chip books for 500/1000/1500. Now if I can just figure out how to get them out....
