There is a process to convincing someone else, usually a stranger, to buy what you own. Many people have Antiques Roadshow or Pawn Stars syndrome; they think they will trip over crap in the attic and find out it’s priceless. There are processes to follow if you want to sell a comic book you believe is valuable. If the comic book does not have authentication by legitimate comic book grading and slabbing companies, then all you did was prove that you don’t know how to prove a comic book is valuable.
I once tried to sell a comic book by pulling it out of a plastic sleeve, touching it with my bare hands, and presenting it to a potential seller. (That guy gave me a look like I had three heads. I was a teen then, but now I understand his reaction.)
