I believe that There are now auto authentications that are computer-based FBI-forensic-like programs that don't allow a potentially subjective 'grader' to give an opinion. I was going to have a signed comic book slabbed and auto-authenticated, but it added a huge expense to the process because of this newer tech that's available. Maybe the cost comes down with wider accessibility in the future?
I guess if I saved used tinfoil and used tea bags instead of old comic books and old baseball cards, the difference between a crazed hoarder and a savvy collector is in that inherent value.
