Thanks all for taking the time and for your learned opinions. My friend sends stuff to PSA to when he sends me autographs scans I look at them from the standpoint of would they pass or not.
I basically told him I thought there was a strong possibility they were all bad. My gut feeling and comparing to a few known good ones I have on file was thus:
Maris, Schmidt - don't like at all and don't/didn't think they would pass
Mantle, Williams - I was leaning towards no good but thought they could pass
Jackson - my only experience with RJ is in person, and usually rushed signatures. Most of the card show sigs I've seen have "44" below or an added inscription - and I was told these were obtained at card shows.
Aaron - he's always been tough for me in general.
I will send the link to my friend so he can read the responses himself. I keep telling him to join, he can learn a lot here, that were (mostly) harmless
but I think he's a little intimidated.
