I am trying to liquidate a collection of 300+ chips for my father in law. I am having a hard time finding out how to value these chips. They are mostly from the northern Kentucky area (Newport / Covington) illegal casinos. Any idea where to find values for these? I have looked on eBay and most are not available there. He has a lot of the prices estimated, but the prices are 5+ years old so I doubt they are still accurate. Any advice or help would be greatly appreciated - I just have no idea where to begin.

Thanks,
Kate
