I just returned from Harrah's Gulf Coast and see that they're no longer using the old Grand Casino room keys, but have these generic-looking Harrah's room keys instead. I don't collect room keys, so I'm not sure if these are used at other Caesars properties or were created just for their Biloxi property. Anyway, I have 1 for trade. (I should have a 2nd one somewhere, but not sure.) Will trade for any $1 chip from my want lists on my webpage at the link below. Please e-mail me if interested. I have other room keys and slot cards listed there as well, so have a look. Thanks.
