Gene's right about the comet chip. Kind of a fun story with these. This chip was used in an ’58 episode of “77 Sunset Strip” titled “The Bouncing Chip” in which a villain named Frenchy LaTour was counterfeiting $100 chips from the Meteor Casino in Las Vegas. Several of us bought these on eBay as UFC's in '04 from a seller in the film industry who didn't know anything about chips or these in particular. Because T.R. King supplied chips as props since they were Las Angeles based, we figured that was the direction to look. These folks also had BTS Ta-Neva-Ho chips as well, go figure. I noticed the chip while watching the show one night in '05 to narrow the Warner Bros. attribution.
