In the dice book that was published in 2004, Sahara dice range from $6 to $400 a pair. Of course dice have been affected by the economy, just like chips have.

Here's a link to Rick Olsen's page that shows Sahara dice. You'll see that he lists them from $8 to $125 a pair. This site was (is?) dice that Rick...one of the authors of the dice price guides...offered for sale.

Condition also affects value. The dice can be "new in package" and still crystallize, which diminishes the value. The scans below shows dice that are in great condition, as well as dice that are almost totally crystallized.
