Can you tell he’s ticked me off?
Or you could email me, I have a bunch of it sitting on my driveway.
I have lots and lots of specimens, from metallurgical anthracite to lignite B - but none for sale, sorry.

I was at the hardware store (ACE), and they had prewrapped (in foil) lumps of coal at the register. Had a picture of Santa, and the words “LUMP OF COAL” on it. Very nice.
