Why this rock is probably not a meteorite:

The rind is much too thick for a fusion crust.

Although the center looks metallic, it's not composed of metal.

Although it's denser than most rocks, it's not dense enough for a rusty iron meteorite.
What is it?

We think this is some type of sulfide mineral that's oxidized on the outside, like meteorwrong no. 78.
