These chips are not a new find, they have been known for a long time. I purchased a half-box each of the $5's & $25's from Washoe Antiques while on our very first trip to Reno/Lake Tahoe many many years ago when Dean and Jodi had their shop located at the visitors center in Reno. Don't remember what I paid for them.
FYI: Contrary to what at least one individual claimed a few years back, I've always divulged what quantities of chips I have WHEN ASKED; but not required to.
You don't think this chip is a great deal as a new member incentive gift?
