I can and do write off as a lack of knowledge incorrect information about what some folks are selling on eBay. It happens everyday, and is usually an honest mistake on the seller's part. The Hard Rock Café opened in Las Vegas in 1990, but the casino wasn't added until 1995. The Paris and Maui Hard Rock Cafés don't have casinos. While they are collectible, they aren't casino chips, nor are they Grand Opening chips. They were all made years after the Cafés opened. ...and I'm trying to figure out what the heck a "Numbered Hologram Airtight" is! It will be interesting to see if the seller edits the auctions to reflect the true nature of what he is offering.
