Counterfeit/altered Cards?

[fkw]

Any card can be counterfeited, usually done on an inkjet printer made from a scan of an authentic card. they can fool collectors in a photo but in person shouldnt.

on eBay etc. these are the most common Doctored reprints
(but some sets ie R319, T206 have been reprinted dozens of times with dozens of variations, so there is no 1 way to tell a fake)
