Hey everyone!

I have a customer wanting to sell a couple items out of his personal collection and he claims they are all 100% authentic but I have my doubts - Mahomes and Brady signing the same ball? Would they even do that?

They do look good IMO when I compare to known authentic autos for the respective players so I would greatly appreciate the help/opinions from respected fellow collectors! I'd like to send them in for authentication if there is a consensus "yes" from people.
