Again, I don't know enough about the La Rue chips to voice an opinion.

Regarding the President Casino New Yorker chips, they fall into the category somewhere between "fantasy" and "real". These were Paulson chips made for a proposed "cruise to nowhere" ship that was to sail from NYC into international waters, where the tables would open. Unfortunately, the licences were never granted, the ships never sailed, and the chips eventually made it to the open market.

I think the website has them correctly identified as "casino never opened".
