Opinions on 3 baseballs

Hello Everyone,

Normally I post on the memorabilia portion of the site, however autographs and autograph baseballs are not my specialty. My father got these baseballs for me, and I was curious if the signatures were authentic? I have no clue on the last one, does anyone know? Thanks for the help and happy 4th.
The Bill Skowron is on a OAL baseball and the Ernie Banks is on a ONL baseball.

Banks looks good, I think Skowron also is ok. Third one may be Pirates/Rangers star Al Oliver, not positive

Ok great. Thanks GG.

The old man did good.:) I think you are correct, Al Oliver signatures look similar to this one.

Thanks for your assistance.

Not an auto expert, but I Think Moose and Ernie looks good.

But I don't think that is Oliver.
I've seen no examples where hIs dot is inside the O.
And the A is always a clear A.

Just my take on it.

Google his autograph images.
