My guess is the the metal was pushed out due to oxidization. The metal seems to be protruding from a crack. I'm thinking moisture made its way into the crack and as the iron oxide formed, it forced the metal to cleave and then pushed the metal up.

Maybe someone on the list has seen this kind of thing before. He bought a Baygorria (Iron, IAB complex) from a dealer 3 years ago. He picked it up recently to find a metal protrusion sticking out of the thing that was sharp enough to prick his thumb. Here's a jpg of his scanned photo. http://meteorites.wustl.edu/baygorria.jpg What's happened here?
