NASA space-flown Apollo medallions were mission-specific commemorative medallions which were approved by NASA and carried aboard the mission spacecraft into orbit. Apollo 15 (July 26 – August 7, 1971) was the ninth crewed mission in the United States' Apollo program and the fourth to land on the Moon. It was the first J mission, with a longer stay on the Moon and a greater focus on science than earlier landings. Commander David Scott and Lunar Module Pilot James Irwin landed and explored the local area using the Lunar Roving Vehicle, while Command Module Pilot Alfred Worden stayed on board.
The medallions were struck by the Robbins Company in sterling silver and ordered by the mission crew as a personal memento of their flight; they were often taken to the lunar surface in the landing module. A total of over 3,000 Robbins medallions were flown into space across the 12 crewed flights of the Apollo program.Photograph credit: Heritage Auctions; commissioned by the NASA astronaut office
