    Does not look like a meteorite, but you can verify this as follows:
    1. Cut a slice through it (can do it on the side a bit so that you don't 
    ruin much of the object)
    2. Look for the Widmanstatten pattern that can only form in space (if 
    nickel/iron, then it should have one...see: 
    http://en.wikipedia.org/wiki/Widmanst%C3%A4tten_pattern)
    3. (if you want to look further): have it analyzed for content. Universities 
    with large meteorite collections can probably do this for you.

    I am *very* familiar with meteorites (I collect them) and this is not 
    looking
    like a real meteorite (iron or otherwise) to me.
