Prices paid for some milestone home run balls - What's the value of Barry Bonds' 756th home run...

What's the value of Barry Bonds' 756th home run ball? While the fan who snared it ponders his options, we offer a sampling of prices paid for some other milestone blasts that wound up in the sports memorabilia market.

It's not likely the Bonds ball will break the record set by Mark McGwire's 70th home run, which was purchased by Spawn creator Todd McFarlane long before suspicions were cast on the Cardinals' slugger.

What turned out to be Hank Aaron's final home run ball, belted in 1976, was picked up by a member of the Milwaukee Brewers' grounds crew who lost his job over his decision to keep the $5 ball.

Eddie Murray's 500th home run ball was sold when reaching that milestone was still considered a rare accomplishment. It now sits in the Babe Ruth Museum.

Bonds' 70th home run ball from his record-breaking 73 homer season sold for a disappointing $14,400 last Friday at a sports memorabilia auction in Cleveland. It originally sold for $60,000.
