Apollo 15 Robbins medal, approximately 1.5″ in diameter, with a raised design of the Apollo 15 mission insignia on the face and engraved on the reverse with the launch date of July 26, 1971, moon landing date of July 30, 1971, and return date of August 7, 1971, encircled by the words "Man’s Flight Through Life Is Sustained by the Power of His Knowledge." The sterling silver medal is serial numbered “192” on the edge and includes its original matching case. Condition is mint state. Accompanied by a signed letter of provenance from Dave Scott, in part: "I hereby certify that the Apollo 15 medallion number '192' included with this letter is from my personal collection and contains silver from the 1715 Spanish Plate Fleet that was flown aboard Apollo 15, July 26–August 7, 1971……Prior to the mission, 304 medallions were struck…due to spacecraft weight limitations, only 127 medallions were actually carried on the flight. However, in my Personal Preference Kit (PPK) I carried a Spanish silver bar salvaged from the treasure of the Spanish 'Plate Fleet' that was destroyed by a hurricane in 1715. After the mission the Robbins Company re-struck the 177 medallions that had not flown and included the flown Spanish silver bar in the mix…Thus the unflown medallions…actually contain this flown Spanish Plate Fleet treasure silver that was carried to the Moon during the mission. This Apollo 15 serial number '192' has been in my personal collection since the mission.”
