Yes, and I get that — although some fakes inevitably slip through.

Also, I am curious what their standard is. If greater than a preponderance of being authentic (50.1% chance), what is it? 75% (clear and convincing)? 99% (beyond a reasonable doubt)?

I'll dig out the 71Topps Fosters I have. I am fairly certain they match yours. I didn't look into his life, but remember thinking how childlike his signature looked when I finally found one, not thinking it might have been this instead.

Here are my Foster sigs. Looks like one may be pre stroke, although only one really looks a bit shaky. I got all from ebay, so I can't provide any back-up info. I was collecting the trophy set pretty hard and Foster was not easy if I recall. Some or all may have been purchased before he died, but can't be sure of that either. All could even be fake for all i know.

At least as of precovid with PSA the expensive ones needed to be OKed by both Keating and Corcoran. I am not sure on the cheaper ones. To me it seems like it also depends on the company. In my experience PSA is most likely to reject. Than JSA. Beckett most likely to accept.

Thank you Curt and Michael.

Curt -- Congrats on a legit pre-stroke Foster and three legit post-stroke Fosters (at least as far as my non-"expert" eye can tell)! Very nice -- although I wouldn't bother submitting the post-stroke ones to PSA or Beckett. I also like your "trophy set" collecting meme. I have thought about starting one of those many times!
