If there was an iron mine nearby, these rocks are likely slag. A Hematite or similar ore will often show signs of oxidation and denudation (being reddish-brown in color) whereas these appear to have a dull metallic luster and are dark grey in color, indicating they're likely a byproduct of the smelting process which contains some iron but not enough to oxidize like a Hematite would.
If you really want to figure it out, see if it is at all magnetic, and if possible perform a Mohs Hardness test. An iron product or ore would be much harder than anthracitic coal iirc.
You could also try to determine if there is any striation of different materials in the slag, or chip off a piece to try to see crystalline structure if any.
A coal would also burn so you could try that as well.
