Lol that was my thought but someone already explained it in another comment. That said, maybe there's a signed copy of the Book of Mormon (well, rather the 'transcriber', lol)... or oh oh, or maybe Dianetics. I bet that'd be worth a ton.
In terms of the New Testament - There's a few writers who based their stories off Macion's Evangelion. And then some more who just made shit up for the sport of Apologetics. After that there were hundreds of scribes who poorly translated and changed the text, either by accident or on purpose.
I haven't seen the Stylometry of the old testiment, but I'm guessing it's almost all stolen from other regious texts. Genisis alone has two competing creation stories.
I'll sell you a signed copy of any book you like provided that it's still in on print and you're not really fussed about who signed it. (Buyer pays shipping, tariffs, taxes, usury and attention)
