One of Hadleyburg’s Nineteeners, and one of the two richest men in town. Harkness is running a political race against the other wealthiest man, Pinkerton. When the stranger wins the sack of lead coins and reveals his plan to stamp the names of the disgraced Nineteeners onto them, Harkness leans over and asks how much he wants for the coins. He then agrees to pay the stranger $40,000, which the stranger eventually gives to Edward and Mary Richards. Harkness ends up winning his political race by printing Pinkerton’s name on the coins and distributing them throughout Hadleyburg three days before the election.
