I remember buying one which resulted in my getting "discovery credit" on the ChipGuide. It was in November when I visited Las Vegas over Thanksgiving weekend and The Dragon had just opened. I shoulda bought a $100 too, and more of the lower-value chips. Had a feeling the place would not last long - but didn't think the casino would close quite as fast as it did. And anyway, buying $100's is just spendthrift.

Best place to find those plaques may someday be flea markets and yard sales.
