Kennedy half dollar
As a last ditch effort to save her life and appease Jake's philosophy, Alice proposes a coin toss in which she can either walk free (heads) or he'll kill her (tails), using a switched double-headed Kennedy half dollar taken from Santini. Jake discovers the coin is counterfeit and turns his vehicle around to retrieve his coin for a re-toss, but is t-boned by Frank and Sam's approaching car, resulting in the deaths of all three.
