The moon's prototypes were originally Nina Ivanovna Koroleva, former director of the Soviet space program
On Thursday, 855,000 euros were sold for sale at the auction in New York at a fraction of three layers from the Moon's Soviet Space Mission.
Sotheby's Auction House said that "moonstones" are the only known documented Moon thing in private hands. They were offered to sell by an unknown private American collector who bought them in 1993 for £ 442,500.
Sotheby said that the buyer on Thursday had another private American collector, but the name was not revealed.
The Auction House said before the sale that fragments starting at about .079 inch x 0.197 inches (2 x 2mm) to 0.39 inches x 0.39 inches (1 x 1mm) could have gotten up to $ 1 million.
The moon's prototypes originally belonged to Nina Ivanovna Koroleva, the director of the former Soviet space program Sergey Pavlovich Koroleva's widow. Sotheby said she was presented with her gift on behalf of the Soviet Union, recognizing her husband's contribution to the program.
Particles In September 1970, an unmanned aerial Luna-16, which drilled the surface to a depth of 13.8 inches (35 cm), was released in September 1970 and issued a core sample, the auction house announced in a statement.
Most other well-known samples taken from the Moon remain with two objects that collected them: United States Apollo 11-17 missions and the Soviet Union using unmanned Luna-16, Luna-20 and Luna-24 missions.
Collectors are paying huge amounts of space exploration artefacts. Last year, Sotheby had sold a zipper bag marked "Moon Sample Return", affixed to moon dust, which Nils Armstrong used in 1969 for the first mission to the Moon for $ 1.8 million.
