Canceled Apollo missions Schirra's crew would fly the C mission, first manned CSM (Block II CSM-101, retrofitted with the cabin safety improvements) as Apollo 7 in October 1968. McDivitt's crew and mission were kept as the first manned development LM flight (D mission); this was planned to be Apollo 8 in December 1968, now using a single Saturn V launch vehicle instead of two separate Saturn IB launches. The E mission was planned as an elliptical medium Earth orbit test of the operational LM with the CSM in a simulated lunar mission to an apogee of , to be commanded by Frank Borman
NASA space-flown Gemini and Apollo medallions also struck, in very small numbers, in 14k gold. These medallions were generally ordered by the mission crew as a personal memento of their flight and were often taken to the lunar surface in the Landing Module. For the duration of the Apollo program, Robbins medallions (3–7 gold and 80–450 silver per mission) were flown into space. Despite the NASA prohibition on commercializing the medallions, since 1995 there have been over 500 internet or live auction appearances of Apollo mission Robbins medallions. Two auction companies account for a majority of the sales: Heritage Auctions (over 200 since 2007) and RR
