You might want go in the "q" range if making a group offer, though.

I have this available for $400 and it is in much better condition than the example in the P&P sale which was Eisenstadt's and was nowhere near a full-blown edge and rim pigment like mine...

I added over 36 codes to Seymour's and that was prior to publication... and used to sell on eBay in '97 without images and only descriptions in grading and during early conventions sold over the phone at $400 and $600 per chip; unseen and only witn a verbal description and never had a chip returned.
