Now I see what you're saying, Ron (First Issue), about the Atlantic City chips being priced at hundreds of dollars over face. I remember having several each of these AC chips seen below and sold them all without question. I got them by asking some casino owners I knew in France at the time. I may have priced them with the help of Archie's AC catalog since I didn't know the market back then, and I did have a lot of cooperation from a few AC collectors as well. So, to answer your question; in my case I tried following the guides of the day along with asking lots of questions.
