A few weeks ago I asked if anyone knew of a find of Cal-Neva Biltmore arodies, which had been showing up on more than usual. I think this auction has answered my question:

http://www.ebay.com/itm/62-1950s-CAL-NEVA-BILTMORE-CASINO-CHIPS-LAKE-TAHOE-NEVADA-ARROW-DICE-RARE-FIND-/141012038492?pt=LH_DefaultDomain_0&hash=item20d4f8f35c

It's not a huge find, but it's more of these chips than I've ever seen in one place at one time. And no $100s are in this group, so maybe they will retain much of their value, even if the $1s, $5s and $25s don't.
