The car belonged to a National Aeronautics and Space Administration instructor who had the samples of lunar and meteorite rock for teaching purposes, the Virginian-Pilot newspaper reported. While the rocks may not look like much, they are worth about 10 times as much as the equivalent quantity of high-quality diamonds.

None of the samples of rock retrieved from the moon by the flights there has ever been sold or given away.
