I got 3 of these with some chips I purchased realized. I put one on eBay for 99 cents just to see if there was any demand for these or of they are just junk.
Non-negotiable means that you have to sell it for .25 cents with no questions asked. I'll take all 3 and I'm willing to ignore the warning and give you a whopping $1 for all 3 chips. I'll even be nice and cover shipping!
Kidding, I have no idea, but I'd bet those chips have some value to them.
Those definitely have some value. Are all 3 the same? the Chip Rack 2015 (i have a newer one at home) lists it as "Q" value or $200-249, though I think that's way too high. I would say they are fairly scarce, but not that rare as they used to be. Condition is a factor. I'd say probably more likely $50-$80 for yours.
Some of the Dunes Card Room fracs are pretty rare. Here are few that i have.
