Crossed Keys

I can't help but think that perhaps a pope may have placed this stamp on an envelope. Chances are though that it was one of the members of the Knights of Templar who did. I'm curious what this cancellation mark looks like in full as it only appears to be a partial imprint. This stamp is from the Roman States, which was governed by the See of Rome. It didn't last long, the Vatican City is all that remains of it. I have several Vatican stamps, but this is the only Roman State stamp which I think may not be a forgery. My other ones appear too clean and crisp to be real. This is #9 in my book, valued at $22.50 if it were(as usual) in much better condition.
