Coins in space: An auction in May of silver medals carried by astronauts on a variety of Apollo missions has brought in nearly $800,000.
Robbins medallions were minted by the Robbins Co. of Attleboro, Mass. These .925 fine silver medals have been produced for every manned U.S. mission since Apollo 7. The medals were paid for by the crews and available for purchase only by NASA astronauts at the time. Medals that were actually flown on missions are especially coveted.
