Nasim Fakhri and Bob Johnson (centsles) coluded with each other to drive the price up of a coin Nasim won on ebay and not pay. This was no accident as both of them bid 1 second apart using an auction sniping web site. There is no way two people could have made such a mistake. Nasim Fakhri has a history of doing this to other bidders as well.
It's also true that Bob Johnson sells NNC slabbed coins on ebay with grossly inflated grades under his user id centsles. New coin collectors are led to believe that NNC is a grading company when they are nothing more than a self slabber. Therefore, Bob Johnson is stealing money from new coin collectors with ebay's knowledge of him doing it.
