Hello Jack, I don't think there are any Bituminous dealers in Michigan, Dennis farms just west of Toledo has Bituminous coal, I think it is about $150/ton, he has Anthracite for around $220/ton.
What type of stove are you planning on burning Bituminous in?? and where in Michigan are you located??
I may have a line on about half a ton of Bituminous, and may have some Anthracite for sale.
Let me know what stove or coal burning appliance you are burning it in.
