Jose Molina kept the bat he used to hit the final home run at Yankee Stadium, wrapping it in a long white sock and carrying it home for safekeeping when the Yankees' season was complete.

The spikes that the backup catcher wore when he clubbed the homer were sent to the National Baseball Hall of Fame in Cooperstown, N.Y., for display. And the baseball? Well, that could be yours -- for a price.

Steve Harshman, a Wyoming state legislator and football coach for Natrona County High School in Casper, has decided to sell the ball at an auction this weekend in New York.

Molina hit the home run off the Orioles' Chris Waters during the Yankee Stadium finale on Sept. 21, and the ball landed on the netting that covered Monument Park.

Harshman told the Associated Press that he has heard estimates that the ball could fetch at least $200,000, and he plans to use the money to pay off debts and help pay for his children's college education.

Guernsey's will auction the ball on Saturday at Madison Square Garden, along with other artifacts and memorabilia from the stadium, which is being replaced by a new stadium next year.

Also up for auction is the Baker Collection, an assemblage of historic documents relating to Yankee Stadium, including 160 original architectural drawings dating to 1921. Yankee Stadium opened its gates for the first time on April 18, 1923, when the facility's first home run was hit by Babe Ruth in a game against the Red Sox.
