Try an auction for a lighter and say it's "like a Zippo" and you'll see a warning and removal in no time. I wonder if Mark's auction for an ashtray with a famous name included, hit the same roadblock. Then there are unauthorized reproductions...

Now there's an idea, maybe write ebay and say the chip is an unauthorized use of the casino name?

No response to a second email to cox.net with the same name, so if I wanted to write to the seller, as suggested by eBay, that's not an option.
