I am asking for 12.44 BTC ($6000 @ bitstamp last as of 3:30pm) for the baseball itself.
That ball in it's condition is mid grade signature and is only worth half the amount you're asking. I have no idea where you came up with $89k for those few items you have that's insane.
Good luck.
The umpire's rule book is a unique item and autographed by more than one person. Check ebay because there are no other ones up for auction. The price of the ball came from the authenticator, JSA.
