autograph signed near death G.C. Alexander

[Lordstan]

These types of questions are very difficult to answer. I think there are 2 parts to the answer.
First, is it worth more and second is how much?
I think the first answer is possibly. What I mean is that if I was looking to collect an example of Alexander's, or anyone for that matter, signature at different stages of his life, then yes, I likely would pay more if it was my only chance to get one. On the other side of the equation is that if all I wanted was an exemplar of his, then no, I would probably not value it any more than any other.
Second part is also significant. Does it double the price or only increase it a small increment? If the difference in value is $10 on a $500 auto does it really matter? Technically it is more, but the amount is so small that it is insignificant. No one can really say for sure until you try and sell it.

Would I pay more for it if I wanted one, Nope. Maybe someone else would. I'd say put it on ebay with a markup above usual Alexander items and see what offers you get.
