HankronIn fact, it dawned on me just after I posted the last message, that a faked overprint would be less likely to duplicate a known one but be a new kind ... Illustrating why documenting provenance is not a bad thing to do, and how significant documentation ('Came from Lew Lipset's 30 year old collection. Card comes with my receipt and a photocopy of his auction page') may actually add significant value to the card some day.
Duly note note that, a large portion of what I do is not just thinking about what and how things have been forged but what and how things have yet to be forged. This type of paranoia and sepculation is normal, and no one should be unduly alarmed.
