A few years ago I wrote to Numismatic News complaining about an advertiser who was offering Paulson's home-use chips as "casino chips" in his classified ads. I explained to the editor that these chips were never used in a casino, that they were made for "home-use" at Joe's Friday night poker games in his basement. The newspaper Editor made the advertiser change his ad copy to read "gambling chips" instead of "casino chips".... which is how his ad reads to this day. John B. is correct.
