Christian Lopez did an unbelievable good deed when he returned Derek Jeter's 3000th hit to the Yankees shortstop.

But it might wind up costing him some money.  A lot of money.

The Yankees gave Lopez four luxury suite tickets to every Yankees home game for the rest of the 2011 season, including the postseason.  In addition, he got bats, balls and jerseys signed by Jeter and front row seats to Sunday's game.

As Bob Barker would say "the actual retail price is........"

It is unknown as of right now if the cache of goodies is taxable or can be considered a gift.  But if Lopez has to pay taxes on the merchandise and tickets, it could run him five figures in taxes.
