It's the quantity. Basically a lot of very rare chips have surfaced and the seller refuses to tell how many he has. In one case, the $25 diswirl, 9 have been sold since June and another half dozen before that. This was an R-10, meaning only 2-3 known to exist. We have seen 15, are there 150 more? Knowing how many exist but refusing to tell in order to artificially inflate the price is the same as lying about the quantity if you know the buyer is relying on bad information, but pokernutt89 will not tell. Neither now will kansaslv. It is possible they are getting them from Becky Binion, who left there with a lot of old chips, but no one knows for sure. As far as I know they deliver what they promise.
