Hey Bobby, Nice job avoiding the obvious fake Mantle!
It's a Zero on the Fudd o meter, LOL. haven't collected Autographs for 4-5 years now. Was going through my 20 Mantle balls (and others) just yesterday to inventory to see what I actually had. Looked some up on E-bay at recently solds and there are still some nice deals at auction without certs. Keep looking at them and one day it will just pop in your head in 1 sec, real/ fake. I just didn't want to put the effort in for others I was collecting, so I stuck to mantle, LOL.
I moved on to trimmed and soaked PSA cards instead. , LOL. Take care and happy hunting. Fudd (Chuck Tapia)
