Do museums buy meteorites?
Sometimes. Museums acquire meteorites by purchase, donation, exchange and fieldwork, and are especially interested in scientifically important or historic specimens.
Museums build their meteorite collections in several ways.
Donations. Many specimens come as gifts from finders, collectors and their families. Donating a meteorite to a museum ensures it will be cared for and available for science. In some countries, donations may bring tax benefits.
Purchases. Museums do buy meteorites, particularly new falls, rare types, historically important specimens or pieces that fill gaps in their collections. Budgets are limited, so they may raise funds from grants, supporters or public appeals. The Natural History Museum in London, for instance, acquired the main mass of the Winchcombe meteorite after the 2021 fall.
Exchanges. Museums trade specimens with each other and with collectors, a practice going back to the nineteenth century.
Fieldwork. Some museums and universities collect meteorites through expeditions, for example in deserts or Antarctica, or after observed falls.
Classification samples. When meteorites are classified, a type specimen is usually deposited in a recognised collection.
What museums look for. Clear documentation of where and when a meteorite was found, legal ownership and export, scientific interest and good condition.
If you have a meteorite to offer. Contact the museum's earth sciences or mineralogy department, with photographs and information. They will advise whether it is of interest. Some museums cannot make offers but may suggest other institutions.
Ethics. Museums follow codes of practice and laws, and avoid acquiring specimens that may have been illegally collected or exported.
Museums are the long-term guardians of meteorites for science and the public.
