The silver ball in the middle is a magnet. From most of what I've read and seen of bog iron, these really don't look or feel anything like that. If they were just bog iron, would a nickle test be conclusive, since bog iron doesn't have nickle in it? The yellow metal pieces confuse me too, bog iron and gold? Just seems too coincidental that I found them all near a meteor site. Sorry for all the questions. I just have a gut feeling that they're more than hunks of iron.
