Victor; The Bally's .10¢ tokens have been around for quite awhile. There are several other A.C. casinos that have ten-centers as well.

Showboat, Trump Plaza, Caesars, are listed in my A.C. Catalog along with the Bally's. I believe that Tropicana also has ten-cent machines on the 2nd floor flight deck and Harrah's recently came out with .10¢ tokens earlier this summer.
