Scott ForrestIt would probably be a good idea to mention some of the characteristics common to RPPC forgeries. You're the expert on RPPC's, so I'll defer to you for the details, but certainly things to consider are thickness, lack of aging (whiteness of the back), photo quality (although this wasn't an issue with mine), and the stamped back (as opposed to printing). The stamped back is what I had the most problem with, so I've included images here of a real one and the forgery. Robert, please point out what to look for.
The key thing is that if it "just doesn't feel right", it probably isn't.
