If anyone lives within driving distance of a coal mine it can be had for 100 dollars a ton, or less. That's about 140 gallons of propane/or 72 cents per gallon equivalent.

We sold lump and stoker coal from our wash plant when I was mine manager for $50/ton. Usually, the buyer drove a pickup and we took extra care with our Cat 980.
Then one winter, we had a buyer arrive in a station wagon. I helped him hand load lump coal.
