Which Monopoly Game Piece Should Go Away?

Hasbro is giving the popular board game a makeover.   The Providence company has launched a "Save Your Token" campaign to retire either the race car, the iron, Scottie dog, wheelbarrow, shoe, top hat, thimble or battleship. 

The company is letting fans of the game vote until February 5th via the Monopoly Facebook page.  We can also vote for the replacement token: toy robot, helicopter, cat, guitar or diamond ring.   Which piece should go, and which new one should be added?
