The chips I am missing that I think exist are the Green and Maroon Camel. Rich it does seem there is a Salamlek Hotel in Egypt. The Sphinx Tours may consist of offices or tours in Cairo- Paris -New York, but I don't see any connection to a Club or Casino. I think they were just put together because of like interest and not related to each other? I could be wrong but wouldn't credit it right away if at all to any other than California at the moment.I found an S.S. Rex chip among other S.S.Rex items from Las Vegas and now think that the chip might be from an Cruise ship from Europe, as the picture showed up later from the same seller? I wanted so badly for it to be from Las Vegas as it would be a one of a kind chip and an awesomely Rare chip and find. So Rich I don't know what to tell you except I don't know for sure and keep looking to see if there is any validation or club to be apart of this coaster? Torrey
