Flown 1936 United States quarter carried on the harrowing Apollo 13 mission, set into a wooden 8.75 x 6 mount beneath a clear plastic shield, with a golden 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. In fine condition, with some scuffing to the plastic. 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.
