ID this black rock

[rochbuster]

I had this rock for a long time, I don't even remember where I've pick it up. So anyone know what is it? It's black with some shiny little spot in it, it's very hard and it's not magnetic.

I'm from Rouyn-Noranda, Quebec Canada, on the cadillac fault and I'm at only 2h from Cobalt, Ontario so there's a lot of old abandoned mines in my area.

Anthracite coal. Not very rare.

Might check the hardness. Can you scratch it with a penny, nail?

When I scratch it with a nail on the botton which is flat you see some white line but they're on the surface, no material come off from the rock, it's too hard.
Maybe it's anthracite coal like Kray Gelder said but when I look at picture of it on internet it doesn't look like it. Somebody told me it maybe serpentine but again I didn't
see a picture of serpentine that look like it.
