A sports memorabilia expert says the baseball used to score the final out in Game 7 of the World Series is worth a fortune. Ken Goldin, founder of Goldin Auctions in New Jersey, says the ball used to secure the Astros first-ever world championship win over the Dodgers is valued at about $250,000.
That may sound like a lot, but Goldin says last year's final-out ball that won the Chicago Cubs their first World Series in more than a century was valued at more than $3 million.
