Who are the tougher living Baseball HOFers?

[hawaiian bam bam]

thank you for your help i appreciate it. im asking just in general on any item to get signed. I ask because i have read on other forums that bobby doerrs signature is starting to get really bad , same with whitey ford, and that tom seaver and johnny bench are really sick and not signing anything nowadays and willie mays and hank aarons signtures look horrible now due to old age and i got a letter back from monte irvin saying he no longer signs due to health issues, and i read al kalines signature looks like he is pissed that he is signing, so that all got me thinking,about what HOFers are now either not signign anymore and hard to get or whos signatures are so bad due to helth that it would be better to pick up an earlier signature on ebay instead of sending ttm or send in for private signing. thanks
