There is currently an auction on eBay for a $1 MATTY chip. It is a light blue large crown chip. I am fairly certain that this chip was used in a California casino in Stockton. The eBay seller claims it was used at Matty's Tropics in Vegas. Both Nevada price guides omit this chip, so I am fairly certain that it is not from Vegas. Does somebody have the story about how these chips wound up in California and why the $1 chip was never used in Vegas? I heard it once, but don't quite remember the whole story.
