SCOTT'S UNFLOWN APOLLO 15 MEDALLION.
Apollo 15 medallion manufactured by the Robbins Company, 1½ inches in diameter, made from sterling silver. The crew mission emblem is on the obverse with the mission dates engraved on the reverse. Serial number "189" is engraved on the medallion rim.
Only 127 silver medallions were carried on Apollo 15 due to a weight limitation on that mission, the first "J" mission which carried the Lunar Rover and numerous new scientific instruments. The full production run of 304 medallions contain the initials of the Apollo 15 mission emblem designer, Italian Emilio Pucci just above the 'R' in Worden's name. The 127 flown medallions contained a spelling error of the landing site name ("Appennines" instead of "Apennines"). As a result the remaining 177 of the 304 medallions originally struck were returned to the Robbins Company to correct the error and were not flown.
Also carried on Apollo 15 was a small ingot of silver salvaged from the Spanish 1715 Plate Fleet wrecks. This ingot was brought back to Earth and added to the melt for the restrike of the unflown medallions (serial numbers 128 to 304). Thus only the unflown medallions actually contain this flown treasure silver. With DAVE SCOTT'S signed provenance note explaining the background to the Apollo 15 Robbins medallions.
