99% sure these are not meteorites but what are they?

My nephew found these in a farm field in East Tennessee many years ago. There’s no record of any kind of smelting factory anywhere around. I don’t have a super magnet but a regular magnet will not stick to it. I have around 15 of these of different sizes. They are all covered in that black crust and it takes a good washing to get it off my skin. One sharp whack with a hammer and the small one broke right in two pieces. It’s very brittle.

Your post worked just fine. I didn't reply because I don't see anything special about the rocks to reply to. Perhaps others will see something, but I don't. Anyway your post worked just fine.

Thank you for your honest reply. I sure wish I knew what these are. There was no signs of a fire or structures either.
