I don't know why these Sahara Las Vegas Letter-tables are hard to find, but I've located only three of them in the HCE mold in several years of looking. This Blue "B" is not in TCR as far as I can see.

I'd put these at more than a value D, too. More like an F.

The Sahra number-table roulettes are still relatively easy to locate, but some colors are scarce.
