Counterfeit/altered Cards?

[almostdone]

Here is an opposite question. Has anyone ever seen or purchased a card as a reprint and it turned out to be the real deal?
It happened to me years ago and wondered if it has happened to anyone else. I thought I would never own a true Ty Cobb so I looked to buy a nice reprint instead. I found someone who had a bunch of cards he was selling as reprints he purchased in an estate suction. He was upfront about them being reprints and never even hinted that they might be real. He had a nice t-206 red Cobb for a few bucks so I bought it along with a Tris Speaker from the same set. When they arrived I studied them and thought they were not just good reprints but really good ones. Being that I had never owned a t-206 before I took them to someone I knew who had once tried to build the set. Upon closer examination and alot of explanation he determined that the Cobb was a great fake but the Speaker was indeed real. Not a bad pickup for $4.
