I would like to know how does someone go about making one of those “great chip finds”?

I live in an area that has not had casinos very long. Yard sales are pretty much out of the question. I placed an ad in the local “penny saver” and did not even get one response! I tried looking in the pawn shops – but they looked at me like I was crazy when I asked if they had any casino chips. Each one replied “Well… (long pause while they thought) if you want a casino chip, you should try a casino. I tried every city within 100 miles of here.

I know people around here (Toronto) gamble. I have worked in casinos in this area since they were legal. Maybe I should change my question to “How do I find a casino chip, without going to a casino”.

Thanks for you help
Happy chipping!
