Sandy Koufax auto ball
All of my balls I am certain are authentic because I buy from private signings. I bought this Koufax from a dealer/collector store with COA but don't fully trust it. I don't know if I should send it to PSA or save my money. Does anyone have experience with Koufax's signature?
