McGwire's 70th homerun ball sold for over $3 million with the juice.... I know its now worth about $25,000 but it did sell for that much. I believe that was the most ever paid.

I agree with Richard, Thompson's "shot heard round the world" would probably fetch a huge sum if they could authenticate it. There was a show on TV about trying to track it down. I can't remember what channel or what it was called. The consensus was that a nun from upstate New York came back to visit her family in Brooklyn I think. She was a huge baseball fan and managed to make it to the game in the left field seats. They said she ended up with it and had it for a while but they think she just gave it away or to some kids to play with.
