Old Man Handwriting?

[jjbond]

So I am new to this hobby.
But as I am looking at collecting signatures, I found that many of the ballplayers lived till their 80's or 90's. And related to that, many of the signatures look...well....like they were written by 90yr olds, and sometimes varies from their earlier years. How does the hobby deal with that? Is there a preference given to signatures that are more legible, from their younger days?

Some examples. Charlie Blackburn lived till he was 89. This signature was from 6 months before he died, but it's more of printing than a signature. Maybe he always wrote this way, or maybe it was just easier later in life?


Snipe Conley lived till he was 83. While I haven't seen other examples of his signature, this isn't that attractive, and looks like old man handwriting:


Bill Otis lived to be 100. This signature looks nice, at the spry age of 92:

But later signatures look more rough (often in blue sharpie, shortened - the 2nd one is on a 100th birthday article)
