I'm not sure any of these were made for a Las Vegas operation. James' book doesn't list Matty's Tropics in Las Vegas. Same owner Matty Matteone is listed for both CA and NV locations in TGT. Could be the California chips were brought to LV and used for a short period. I would consider them California chips. However, several collectors have expressed differing opinions regarding Matty chips on this bb in the past.
