Their price has doubled in the last 6 months and shipping would be a nightmare, but I can attest to the quality of the Kayne and Son's (Blacksmith's Depot) coal. I'm not sure where they get it, but it is clean and hot.
I've been using if for awhile, as I picked some up in person right before the price increase. It cokes great, and I only have to mess with cleaning out clinkers before my next fire. (A sin, I know. Surely I will be struck down). I get only about 2 quarter sized lumps of clinker in a 3-5 hour run of the forge.
I don't know how far Grundy, Va. is for you, but my local guild gets some pretty decent coal from there for $80 per ton. May or not be worth the drive given current fuel prices. :cry:
