Doug,

ChipGuide's Opening Date will be adjusted to 1944.

Check out these Archived threads regarding the $5 Nevada Biltmore, dots mold chip.

These links give some insight into the history of the Nevada Biltmore.

These 2 are from Archive 11.

Ever since the postings in Archive 12 (2004/2005) I had an active, continuous eBay search for Nevada Biltmore. Aside from the few hits noted in the Archives, there have been plenty of hits for postcards, dice and occasionally for matchbooks and menus, but no additional hits for the $5 dots-molded chips. I still have serious doubts about a box of 100, but hey, stranger things have happened in this hobby.
