Hi, I found this the other day. Its shiny, like gun metal. Its soft, scratches into a fine powder.
No smell, not very heavy.

Found near an old mining area, do you think it could be electrum or some kind of silvery compound?
It can write on paper like a pencil

I have googled and i think it is Anthracite, due to its density of 1.5

Graphite perchance?

I would bet on what it is NOT in my OPINION - Anthracite, BUT I would not bet on what it IS!
I might guess Antimony.
