The Queens man who caught Barry Bonds’ record-breaking home run on August 8, is now thinking about holding on to it rather than selling it. The ball is valued at $500,000, but the sentimental value may be worth more to the college student who was on his way to Australia when he attended the game. There are also taxes to think about. Murphy revealed he was considering keeping it during a “Today Show” appearance. Murphy’s grandfather, a retired NYPD cop says he’s hoping he’ll sell it to give himself “a nice head start.” Bonds was headed for the Hall of Fame before he broke Hank Aaron’s career home run record at AT&T Park in San Francisco. But Murphy called number 756, “the greatest American sports accomplishment in history,” Murphy said, explaining why he may not sell it. Perhaps, but what about the ‘greatest American sports accomplishment not aided by Deca-Durabolin or Winstrol or human growth hormone’? That’d fetch 500K, at least.
