I've always felt that the greatest image of a historic baseball event doesn't capture the event directly. I'm referring to George Silk's image of the 1960 World Series for LIFE (disclosure: I own it). What photographer would leave the stadium for a shot of the final inning of the World Series? Silk missed Mazeroski's home run, but got something much better. I think it's one of the greatest baseball images ever taken.
As to your question, while the negative was "there" at the event, there are only a handful of negatives that would sell for more than a vintage print--I'm thinking of Nat Fein's negative of 'Three Bows Out' and Conlon's negative of Ty Cobb sliding into Jimmy Austin.
