It is difficult for me to believe that these relatively easy to come by generic chips would have been put in play by the LandMark--although that might explain why the casino expired. The chips were manufactured. I have a 1915 Harris Catalogue showing the unbroken "champion" and you can see your "champion" chips in Seymour's Antique Gambling Chips in a 1905 American News Catalogue (p. 417).
