This Apollo 15 commemorative medal was struck by the International Mint, an American company. Apollo 15 launched on July 26, 1971, and returned to Earth twelve days later. David Scott, Alfred Worden, and James Irwin were the astronauts. It was the ninth human spaceflight and the fourth lunar landing in the Apollo program.
Space medal collector Thomas Becker donated this medal to the National Collection in 1972.
This object is on display in James S. McDonnell Space Hangar at the Steven F. Udvar-Hazy Center in Chantilly, VA.
