Opinions on the authenticity of a Mantle autographed ball
 

I picked up a small box lot of vintage baseball from an estate sale (I know instant red flag, but I bought for the cards the ball was an extra) The cards all seem legit, no reason to think their not, there was nothing amazing in there, just some lower/average grade stars and HoFers from the early 60s and 70s.

This ball was in the box as well. It's a 1978 World Series ball. Sigs I can decipher are Mantle, Billy Martin and Graig Nettles. I know there are prob more fakes than real Mantle autos out there so here I am. Any chance this is legit or no.

I'm not even close to knowledgeable about vintage autos, I'm sure some of you may think it's a laughable fake but I have no clue. I usually use blowoutforums but I'm here for the experts!
What do you guys think?

Thanks,
Jeremy

I'm leaning toward good on that.

The autograph visible to the right of Billy Martin, is Paul Blair.

Steve

Not authentic.

Thanks I wasn't sure on that one

I don’t like this either

Does anything stand out to you? Overall does it look wrong?

That isn't Blair

Any idea who its supposed to be? I checked on his and it looks way to smooth to be Blair. His never seems to look that clean

The Billy Martin looks weird to me too.

First name could be Dave or David, or even Darrel.
