I’ll start by saying I don’t trust psa/dna. I’ve recently seen forged Unitas and ray nitschke autographs slabbed in psa/dna holders so my confidence in the company isn’t at 100%. That said, I’ve seen a few questionable mantle autos get slabbed too. Including this one attached. What do y’all think?
don't focus on the M's. Yes, there are some definite forgery styles where the M's are elongated repeatedly, but in those cases, the entire signature is off. In this case, its a no brainer authentic Mantle.
