NASA space-flown Gemini and Apollo medallions
NASA space-flown Apollo medallions were mission-specific commemorative medallions which were approved by NASA and carried aboard the mission spacecraft into orbit. Apollo 17 (December 7 – 19, 1972) was the final Moon landing mission of NASA's Apollo program, and remains the most recent time humans have traveled beyond low Earth orbit and also the most recent time humans have set foot on the Moon. The crew consisted of Commander Gene Cernan, Lunar Module Pilot Harrison Schmitt, and Command Module Pilot Ronald Evans

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
