1 Dollar (Christa McAuliffe)

The Teacher Who Was Going to Space — On a Silver Dollar

She was an ordinary social studies teacher from New Hampshire — chosen from more than 11,000 applicants to be the first private citizen in space. She never made it. Thirty-five years to the day after the Challenger broke apart, the U.S. Mint released a silver dollar that carries her face, three students looking up at her, and the line she lived by: "I touch the future. I teach."
