The Ice Cream Dime

San Francisco, 1894. The Mint will strike just 24 dimes this year, and one of them will become the most famous dime in America.

Follow it through three pairs of hands: Mint superintendent John Daggett, his daughter Hallie, and the ice cream vendor who takes it in change. After each big decision you'll see what happened, and whether it comes from the record or from the legend.

Watch three numbers: Survivors, how many of the 24 are still out there; Grade, your dime's condition; and Talk, how far the story spreads. Let the Talk climb too high, and Washington may want its dimes back.
