I understand and am fully aware of Graham's real-life persona. To reiterate, he did nothing in life, baseball career or otherwise, to make his signature so valuable. Kinsella's fictionalized treatment of him is what catapulted the value. Faust's zany antics and McMullin's role in baseball's biggest scandal are such that their autographs are fully deserving of carrying the premium that they do (actually, there aren't any Faust sigs out there as far as I know, but that's not the point). Just because I don't necessarily agree with the premium attached does not mean that I fail to understand why . 
John,
Funny you should mention one-gamers! I also avidly collected them! My favorite is a guy named Icehouse Wilson, who made his lone big league appearance with the A.L. champion 1934 Tigers.
