Anyone know whether the two top chips in this picture were ever in use? This is from a pic in the old Las Vegas magazine in 1962 (on eBay this week). The bottom chip from the Fremont does seem to be listed in both chip references, but not the top two. I know it's dangerous to take pictures from the print medium as representing something real, but wondered if any of the 'Big Chip' collectors reading this could verify the Sahara and Tropicana chips.

Might be worth a listing in TCR with a note that their existence is not yet confirmed.
