I can tell you that the '72, '73 and '74 Mays are ghost signed by his wife. Pretty typical for cards signed through the mail from him back in the '70s and '80s. An easy giveaway is that the 'i's in Willie are dotted with a circle.

And like one of the posts above, I wouldn't bother with cards that are signed lightly in ball point or for guys like Fingers, John, Perry etc where you can still get those pretty cheap now, either directly from them or on the secondary market.

Bench used a stamp for a while and I think it was usually black. I definitely like the ones in blue, you'll need to look closely at the first couple in black and make sure they are not a stamp.

I'd look at the 'bay and see how things are selling - are most of the cards in a TPG holder or are they raw? Do they match the style of the ones you have. Sometimes players will always (majority of the time) sign the same card in the same place, sometimes not. Don Sutton will more likely than not sign right over his own face.
