I have these four different Dunes chips. They're made of plastic, and each have a hole, perhaps for a keychain.

I'm wondering if these might possibly have been sold in the gift shop ? I don't think they can be considered "ad chips" or fantasy chips. They have a denomination on them, but Im sure they're NCV chips, even though they don't say it.

Anybody know about these?

Alan....any TCR numbers for these?
