Comment on Have you ever seen coal in real life?

We once had a very old house with a cellar that was not used and not built for living there in any way. So you had plain rock walls and it was pretty moist. I do not know why but there was a single basket of coal down there. So I have seen black coal but I have not touched it.
Crude oil I have seen too back in school. My teacher had a sample to be able to show it.
