This auction (from the same guy selling the Palms silver strikes) looks awfully suspicious. He says he has 23 of these sets, and he's using the exact same picture used by another seller for a set of poker chips supposedly owned by Art Buchwald.

Here's the suspicious looking auction link:

I e-mailed the seller. I'll let you know if I get a reply.

The top photo is from the Art Buchwald auction:

It looks like he might have sold some already.
