My best find was a chip. About 10 years ago we were in Las Vegas, staying at Circus. In the morning we always went for a long walk and Cindy needed something at Walgreens. As we were entering the store I noticed a chip outside by the front door. I figured it had to be fake but the Palms cashed the $100 chip with no questions. I still have no idea why that chip was still there after all of the bums going in and out of the store didn't see it.
