They are from the Argosy Casino in Lawrenceburg Indiana. Long story short....they purchased these chips before realizing that Indiana Law states that the name on the chip needs to be the same as the license holder of the casino. The license holder is the "Indiana Gaming Company, LP" as you can see on the chip that started this thread.. The "Argosy Casino" chips were canceled and sold at Paulson retail stores years ago. I'm been piecing this set together for a year or so. If you look at my chips they say "Argosy Casino" and have all been canceled with either a hot stamp or a hot stamp and holes and notches.
