There is a *different* eBay account - and possibly more than one - that seems to have illegitimate listing of Binion’s chips, as seen here (the pictures are pictures of chips on someone’s monitor):

I’m certain Brie simply didn’t click on the link showing your son’s auctions to realize that the one Joel posted earlier is a perfectly legitimate account.
