Jim, The Plaza had a free pull slot machine outside the front doors that took these tokens about 15-20 years ago. I remember a guy gave people one token at the front of a line. That person would walk up to the machine and get one free pull after inserting the token, can't remember the prize. I took the token and walked up to the machine and stepped past the machine and into the casino. A guy chased me and said I had to give him back the token. I told him it was a gift to me from the casino and just kept walking out a different door he still followed me for a while and finally gave up. The guy wasn't security, just a guy in a suit who was running the free pull with two other guys. So that's how I got mine.
