I agree with almost all of the above, any player that died prior to the 1980's card show BOOM's autograph would be considered kinda uncommon. However even Nellie Fox , Satchel Paige etc are are tough sells and don;t command much on the autograph market. Clemente of course does but I think this has to do more with demand than rarity as he was a pretty good signer. Jackie Robinson same, but the market was flooded with hundreds maybe even thousands of signed Jackie checks so it was almost like he did a couple card shows anyway.
So the post war toughies then become the umps and executives that typically were never asked to sign autographs. Then work your way back from there using the date of death as an indicator from fairly common to , mid range , tough and impossible. Of all of the Hall of Famers many of those fall into the catagory of "no known examples" of their signatures have ever been offered to "less than a handful" exist , the production of many of the all time toughies like Addie Joss, Tim Keefe, Mike Kelly, Buck Ewing etc etc has created a false sense that there are more of their autographs in existence than there really are.
