First of all, certificates of authenticity, LOA’s, etc are basically worthless. I’ve seen LOA’s from the athlete themselves and the item was no good. Now getting to the subject at hand, it’s absolutely true that Peyton’s signature has changed dramatically from his days at UT. I have multiple exemplars when he was a student athlete, and while very different from his NFL signature, they do not jive with the OP. Bottom line….if….IF….that signature is good…which I do not think it is….it’s basically worthless because no one will buy it. I’m sorry to be the bearer of bad news.
