Thanks for the input! I should add, all the balls I have posted are from the collection of a deceased family member, who I think was likely duped when buying many of them. I'm learning as I go, but any reply, even if it's to say it's a blatantly obvious forgery, is appreciated - just to affirm my suspicions and determine whether I need to bother following up or seriously authenticate any of these. I know it can be quite a process and expensive to get them professionally appraised, so I would rather avoid doing so if the answer is obvious to experienced collectors. I've been appalled at what I've learned so far about the level of fraud in this hobby!
