This 1936 quarter was flown onboard the harrowing journey of Apollo 13. The coin is secured behind a clear plastic shield affixed to a 8.75 x 6 wooden plaque, above a gold plaque that reads: “This 25 cent coin was the first U.S. coin to fly on the aborted Apollo XIII mission. Safe return to Earth was attributed to the LM 7 power system, April 11, 1970 to April 17, 1970.” The plaque is also engraved with the crew names and facsimile signatures. A tangible piece of history that bore witness to what might have been one of NASA’s most horrific failures, but instead led to its greatest ingenuity. RRAuction COA.
