A few days ago a new T206 ghost was posted on the main forum that caught me as suspicious (new boardmember, different player f/b, name on back, ghost was not limited to one "detail" layer). I let the usual buyers know I was interested in the card and if they would hold off for a bit..to which all did (thanks guys!).

After a few days the owner sent me additional scans of a "more expensive" card and that he had several errors and ghost available. This is where he got greedy. A Cobb ghost

He didn't invert the image, used a top tier HOF, a super print on a 150 series back….and was dumb enough to use a card he just bought on eBay - 6***d(13).
Be really careful when buying these oddballs.....especially overprint & ghosts....the hammer prices are high enough that this likely won't be the last fake.
