1. The Genesis Block Newspaper
It is definitely a top historical piece that deserves residence at museum. Only so far 8 of them found I believe in existence but I may be wrong.
I run the site on the Genesis Block Newspaper collectible. We’ve managed to track down and verify about 7-10 copies. No more. So you’re right on about that!

FWIW: Always require full supply of the original inserts along with it, if you’re ever in the market to buy one.

PS: sorry OP, I didn’t know which category to put this item as it is a newspaper.
