I agree with Debby. Collect what you like or what strikes you as cool. Having been a 21 dealer in the late 70's, I have a special attachment to casino chips and cards since they were the tools of my trade. I only wish I had been a collector in those days! It is my connection to those days in Las Vegas, even though I am back in my home state of Ohio since the early 80's. I don't collect as an investment, I collect because I enjoy it.
