Stolen and missing moon rocks
Of the 270 Apollo 11 Moon Rocks and Apollo 17 Goodwill Moon Rocks that were given to the nations of the world by the Nixon Administration, approximately 180 are currently unaccounted for. Many of the Moon rocks that are accounted for have been locked away in storage for decades. The location of the rocks has been tracked by researchers and hobbyists because of their rarity and the difficulty of obtaining more. Moon rocks have been subjects of theft and forgery as well.
