I am fairly new to this hobby and have some questions regarding chips from the Dunes Casino.

Now being that the Dunes has alot of history and the fact that the chips themselves are one of the nicer chips ever made I figured that the prices would reflect that. But then I see sites like this one below and I scratch my head.

Can I really get a real uncirculated $100 Dunes chip for $10 or a $25 uncirculated chip for $6?

Are these actual chips from the casino or has someone reproduced them?

Also assuming these chips aren't real, could someone point me in the right direction of where I may be able to aquire some real Dunes chips. It would be much appreciated.

Thanks.
