Heritage Auctions has put a price tag of $340,000 to $380,000 on the moon rock, while another 81-kilogram meteorite nicknamed “The Scream” is estimated to fetch anywhere between $175,000 and $225,000. Meteorites from the Macovich collection, one of the world’s largest groupings of iron meteorites, amount for more than half of the ones that are up for sale. Museums in London, New York and Paris and The Smithsonian in Washington have meteorites on display that are part of this collection.

Pitt, the owner of the meteorites, wants to part with his collection as he wants to popularize meteorites. He said, “I knew that the only way I would be able to attract interest on the part of the public was to offer objects that were more visually captivating.”

The auction has material from six meteorites which are known to have originated from a large asteroid Vesta. The auction is going to have meteorites from Moon as well as Mars including a fragment of the Tissint meteorite, which fell in Morocco in July 2011.
