My dad and I are arguing at how much the final home run ball hit at yankee stadium could fetch. I'm saying around $50,000-$100,000 and he said maybe around $500K. What do you guys think it could be worth. I know if the other team player hits it the value may go down but if A-rod or Jeter were to hit it i think the price would go up alot. Would like to hear your opinions. Thanks
