DiMaggio, Williams, Aaron, Koufax, Mays Autograph Authentication
 

Hello,

I have a handful of baseball signatures that I am trying to ascertain whether they are authentic. All of these check out to me, but opinions from those with more expertise would be greatly appreciated. I believe the Joe DiMaggio plaque and signed ball is one of 361 in a 1998 limited edition, but I would still like opinions on the authenticity of the autograph.

Thanks in advance.

Joe is good. The rest are bad.

Thank you for the help. My short-lived “career” of self-authenticating and buying non-authenticated balls may have come to an end. Luckily, the Joe checks out and the Yogi Berra I got has an MLB AR147650 hologram sticker, indicating that it was signed at a Dec 01, 2001, private signing event - so that one should be the real deal along with the Joe.

Any second opinions (concurring or dissenting) prior to me scrapping the Williams, Aaron, Mays, and Koufax balls.

Thanks once again.

Don't like Aaron or Koufax. Not expert on the rest
