20 Dollars Mission Apollo XII

Apollo 12 landed on the Ocean of Storms in November 1969, just four months after Apollo 11, and remains notable for the lightning strike that hit the Saturn V during launch — twice, within 36 seconds — briefly knocking out the command module's fuel cells before mission controllers in Houston guided the crew through a manual reset. Pete Conrad and Alan Bean spent just under 32 hours on the lunar surface, recovering hardware from the unmanned Surveyor 3 probe that had been sitting there since 1967.

Liberia issued a long series of commemorative dollars around 2000 tied to the Apollo program. KM# 661 belongs to that run.
