Autographed Card Question: How Important is Legibility?

[Topnotchsy]

To me it's less about legibility and more about whether it looks similar to regular signatures from that person. Many players like Stan Musial saw major deterioration in their ability to sign before their passing, and while it is great they still signed, I'd much prefer a version that is more standard. (Of course in some cases a player's autograph changed over time, like Mantle's. For player's like that I prefer an earlier version, even if it is not the most recognizable version of the person's signature.)
