These were still in use at Tropicana last year. they still may be in use. I saw the machines they were used in. So , I took back the $20 of those tokens that were in my duplicates. Played for a while , then took about $40 of them to the cage & got my money back. There was a mixture of the 10c tokens from some of the other AC casinos. I could not give them away at that time.
