1957 Yankees Spring Training Baseball: Mantle, Berra, Ford, Stengel

[shernan30]

I'm in the process of evaluating this 1957 Yankees ball for a friend and could use some input for the members here. Being a card collector, I'm not sure if this is something I should have authenticated and if so, where should I send. I'm also interested in an approximate value.

Any thing would be awesome.

Thanks,

That Mantle may be a clubhouse, I'm not very good with earlier Mantle signatures but it seems a bit off for me.

I wouldn't touch it because of the Mantle and the Ford. Can't see Berra well enough from that pic.

That Mantle signature looks very familiar. Seems strange that there would be clubhouse signatures on a spring training ball.
