So sometimes I'll see graded, vintage rookie card autos where the player died around 5 years ago, and he was known to be a highly active signer 10-20 years ago. But the cert number on the PSA slab would suggest that the card was graded 2-3 years ago. It strikes me as a bit odd that someone would wait more than 2 years (and probably much longer than that) after getting an already valuable rookie card signed before getting it authenticated. In those situations, I can't help but think that an alternative explanation is plausible, if not more likely.
