Why are pencil autographs from the pre-1950s era so disrespected by collectors?

[Jerry42]

As to my love of pencil autographs from the 1940s-early 1950s, I should add that as a kid in those years, I brought a pencil to every game with my lined, small note-pad, and the pencil autograph reminds me of those experiences. And for me, that's what collecting is all about. So, although I have nothing against a Jackie Robinson autograph in pen, I like the pencil, especially because of the price reduction. And no matter what anyone thinks, those pencil autographs last -- better than some of my ink autographs exposed to light on my walls.

I also like the flavor of the times, and don't care about white balls and small wrinkles in cards (although I do keep my eye on value).
