I'd like to trade any or all of these Hard Rock Cafe chips for some of the series I don't have, which is most of the more recent ones. These aren't from the casino in Las Vegas but were sold on the Web by Hard Rock. I believe the four in my scan are now no longer available. If you don't have any of the rest of the series to trade, I'd sell these for $10 each. Drop me an e-mail if you are interested.
