Should I sell a meteorite I found?
That is your choice, but first make sure you legally own it, get it confirmed and classified, and consider whether a museum or research group should study it. A fresh fall in particular can be scientifically precious.
Finding a meteorite is a rare thrill, and deciding what to do next deserves some thought. There is nothing wrong with selling a meteorite that you legally own, and the meteorite trade has helped bring many specimens to scientists and museums. But a few steps come first, and the first is ownership. In many places a meteorite belongs to the owner of the land where it lands or is found, so if you found it on someone else's property you may need their agreement. Some countries treat meteorites as state property, require finds to be reported, or restrict sale and export. Laws differ widely from country to country, so check what applies before doing anything else.
The second is confirmation. Most suspected meteorites turn out to be Earth rocks. A museum or university geology department can tell you whether yours is genuine, and a qualified scientist can arrange official classification. That requires depositing a small reference piece, the type specimen, in a recognised collection. An unclassified stone is difficult to sell fairly, because buyers cannot be sure what it is.
The third is science. If you saw it fall or found it soon after a fireball, contact researchers quickly. Fresh meteorites contain short-lived chemical clues that fade within weeks or months, and the exact recovery location helps calculate its orbit. Some finders choose to donate, lend or sell their meteorite to a museum so that it is preserved and studied.
If you do decide to sell, keep careful records of where and when you found it, get more than one opinion, and be wary of anyone pressing for a quick deal. There is no guarantee a meteorite will fetch any particular amount, so think about what matters most to you.
