Is this Roger Maris signature authentic?
 

Anyone have an opinion on if this Roger Mari's signature on my baseball is authentic?

Post some additional pictures of the ball please and that will help. I believe that's a Charles Feeney ball (1970-86 NLP). Maris retired after the 68 season, so it may help if you show the other signatures.

I uploaded some pictures of the ball and the COA

Novice opinion: good.

Good.

I think it's definitely good

The M looks funny, but I believe it is good as well.

Yup - Maris is good

the maris is no doubt authentic.

Not questioning the opinions above and this is only for my edification, but do almost all the signatures appear to have been signed with the same pen?

Would be consistent with the idea of passing it around in the clubhouse.
I have a Maris I'm planning to submit to PSA tomorrow. Worth sending?

Looks good to me! :)

Looks Good !

FWIW, mine in the picture above just got reviewed by PSA/DNA and was tagged Questionable Authenticity, their term for fake.
