FLOWNGHAIR

The first penny flown into space might also be the oldest and most valuable. A 1793 Flowing Hair cent — only the second style of penny issued by the U.S. — was flown for a coin collector by way of the Gemini 7 crew's flight surgeon in 1965. The already rare one-cent piece, which was packed inside the mission's inflight medical kit (without NASA's prior knowledge), was sold at auction 50 years later for $82,250.
