Need helps IDing these baseballs
 

Got a few for practically nothing today. Sammy Sosa, Paul O Neil, a Marlins signed ball ( no Cabrera), Walt Weiss, Chris Chambliss.. Need help with these sigs though.. The dirty ball is one of the signatures on the Marlins ball. Much appreciated.

First 2 look like McGwire although I can't speak to their authenticity

First one is Mark McGwire.

McGwire on left is good, McGwire on right is not.

Thanks for the feedback..I don't think the one on the right is fake, the lady said she used to work for the Red Sox, but hey, who knows, she could of sold me!

I have several in-person McGwire's ranging from when he was in the minor leagues to his coaching days in St. Louis. I've never seen one that looks like that second ball. The first one looks legit.

The bottom one sort of looks like Barry Larkin, but I don't think it is legit unless it is an unusual version of his signature.

The bottom ball has Gary Sheffield and Jeff Conine on it as well..that's why I thought Barry Larkin would be odd
