Jodi BirkholmI'd be quite surprised if PSA had any examples in their files. You may want to ask Jim Stinson or Gary Schulz. Do an online search for Stinson's webiste to contact him.
I wasn't trying to say that the signature is a forgery, as the ink certainly does appear to be from the right period. Personally, though, I have no experience with this boxer's autograph; I was just making an educated observation on what I saw. As I said, ask Stinson or Schulz, or perhaps Craig Hamilton. I'd try the first two guys first (I don't have contact info for Craig).
