One lucky and very, very rich fan is set to walk away with baseball history ... as the home plate Barry Bonds stepped on after hitting his 756th career home run is up for auction -- and it's estimated to sell for $100,000!!
Bidding for the base -- along with a signed ball from the '07 game -- both come with letters of authenticity signed by the former San Francisco Giants slugger himself ... and the package is currently open for bidding via SCP Auctions.
"This is the actual home plate from the San Francisco Giants and Washington Nationals MLB game on August 7th, 2007, at AT&T Park where I hit my 756th career home run in the contest, passing Hank Aaron for sole possession of first place on the all-time MLB home run leaderboard," Bonds' letter says.
