I don't care how much I want someone's autograph. Why would I want a signature like that in my collection? Authentic or not! No wonder they want someone's else's COA on it.
James, I know this sounds crazy, but sometimes when you see an autograph that looks nothing like the celebrity's normal signature, and at the same time not neat and pretty (like a secretarial)....chances are it's not a forgery. The authenticators will see something about that graph that screams real but rushed.
You mentioned Jennifer Lawrence at the start of this thread.....she is perfect example of a celeb whose authentic inperson graph can be an utter disaster, but I can still spot a real one hidden among 100 fakes.
I just have to jump in here...
I would hope that PSA gets their exemplars from somewhere other than Google. So even if Google came up with nothing, I would hope that would have no bearing on PSA's ability to authenticate a particular piece.
As for your theory, there's only one way to test it.
I wonder how much it would cost for PSA to provide further justification for their opinions? I feel that they are typically the best source of authentication that is readily available (I typically start with Epperson if it's rock-and-roll), and having their stuff encapsulated or slabbed is as ironclad as you can get to maintain that authentication, but if they are not available to be challenged for their opinions that people find questionable, as evidenced by this thread, then they will not be able to maintain their credibility.
If this is happening because they are authenticating things in a manner that is "Willy-nilly" then they probably won't be around long. If they, instead, can provide good explanations, then they will be able to deserve and maintain their positive status.
One can't expect PSA to be open to doing all challenges for free, so I wonder what more they will need to do them. I'll chip in, but my bottom line is I feel that they are a very necessary service to have - as long as they're legit.
