Any Vintage Boxing Experts?

[raiderguy10]

I recently bought a bunch of boxing autographs from the 30s-70s. I have never collected or owned any vintage boxing autographs but thought it would be fun to research. I was able to identify the following signatures...are any of them worth getting authenticated by a 3rd party at all (ie rare/valuable)? I couldn't find comparables on many of them.

Eddie Cool
Eddie Zivic
Carlos Zarathustra
Phil Terranova
George Chaney
Freddie Steele
Kenny Lane
Lou Ambers
Sammy Angott
Carmen Basilio
Sal Bartolo
Tony Barone
