Ignorant questions: Coal doesn't go bad does it? This wouldn't be coke would it?
black, hard, shiny = anthracite
I've been burning thru a several tons from a basement in an old house that's been there since the early 1950's. Kind of a shame, boiler is next to the coal room perfect setup for a stoker. It burns no different than "new" coal from a bag.
There have been a few pieces that look like charcoal; very rough edges, crumbles easily. Not sure what they are but they burn. I've heard old timers say there was "lots of crap in coal back then". The pile I've been mining seems to agree - at least a large coffee can of nuts, bolts, broken bottles, etc I've pulled out of it so far.
The mouse carcasses are just more BTU's.
