Sao Joao Nepomuceno is an absolutely amazing (IVA-an) meteorite, both from its appearance but also for the story that goes along with it. It was a 1960s fall from Brizil, when a local farmer discovered it by rolling over it with the wheels of his cart and he realized it did not break apart like other rocks he was rolling over. Once he realized it was iron he brought it to the Mayor who then showed it to a visiting engineer who then confirmed it as a meteorite! Most of it is now in the Museum Of Natural History in Rio de Janeiro. Here is a little more about this stone... https://www.lpi.usra.edu/meetings/metsoc2004/pdf/5090.pdf
