He has lots of nice chips for sale, but he appears he's using the rarity numbers from James' price guide, which is almost 6 years old now. That's a valuable book for the hobby, but many of the prices are now irrelevant. And most of this guy's auctions aren't likely to sell because the market has changed so much since 2009.

I got into a discussion recently with an seller over his description of what he called a "very rare" $1 horseshoe mold chip from Barney's Lake Tahoe. He described it as an R-9, with only 4 to 7 known. I mentioned to him that a current auction contained 600 of the same chip and that his chip, which he had priced at $700, was anything but "very rare." He got upset, saying he didn't own the Chip Rack and that he was using James' book because it was the most recent version of that guide. He eventually lowered his asking price to $90 but still called it "very rare." Few of his auctions sell.

Just my opinion, but I think the only way to stay reasonably on top of what Nevada chips are selling for is to use the Chip Rack. I still have my copy of James' book, and I refer to it often, but not for current pricing.
