Paulson couldn't use that mold to make chips for anyone but the Dunes. Unless Paulson owns the copyrights to the Dunes logos used in those molds, they have no right to license the reuse of the logo'd molds. Only the owner of the Dunes logo copyrights has that ability. But, that's all secondary to the real issue. You can manufacture fake currency that looks similar to real currency without it being considered to be counterfeiting, if security aspects of the real currency aren't duplicated in the fake currency. That mold with the corresponding cross hatching is too close to the original real casino currency. I don't care how much the fake chip inlays may differ from original chips. Printing copies of original inlays and placing them on the new fake chips would be too easy to do.

This is just plain wrong in my opinion. If someone wants to make clay chips for home sets, try using some level of originality. Don't copy real casino chips.
