What % of signed cards on ebay are forgeries ?

[yanksfan09]

Too many variables to even give an educated guess. Only talking cards? or all signatures? Star players? no name guys etc...?

I'd assume almost all manufacturer authenticated modern day cards are real. like the topps certified cards inserted in packs. However it gets a little more dicey when you get into the old player cuts that are inserted into modern card creations.

Unauthenticated autographed cards of major stars would certainly be the biggest area of fakes....
