Signed Ball. Dick Groat, Mickey Mantle, etc ?
 

I can make out Groat and Mantle but no idea on the rest. Obviously authenticity is a huge question too. I appreciate any input.

The ones in black look pre-printed on the ball. The Brock doesn't look right to me but the Mike Shannon looks fine.

I agree 100%

The ones in black are rubber stamped, and the Lou Brock doesn't look good to me.

How about a pic of the Medwick?

Signed ball -Authenticity an issue
 

Yes, the authenticity is in question. In a very big way !! This is a facsimile stamped baseball. The strange thing about it is some one has "traced over" some of the facsimile stamped "signatures" to make them a darker black and try to make them more authentic looking. The only real signature is the one signature in blue which appears to be " Mike Shannon". The Lou Brock signature is traced over with a blue sharpie or marker.....and I'm not so sure the facsimile sig under it is a machine stamped Brock. The blue sharpie does a better job of obliterating the underlying name than the black sharpie or marker.

I never thought about it but a forger could take a facsimile stamped "signature" ball and go over the signatures with a blue sharpie and make it appear to be a more legitimate signed ball.

The Robinson and the Herbert look smeared towards the end of the autos, like the ball moved as they were stamping it.... Placement of all looks fishy also...
