Guideline.........LinkHhappy, I say this is very good price guide line. Kentucky and WV is cross the ocean, so if the price has too big difference, then WV miners will ship the coal to Kentucky. If Kentucky has so many mines, then the prices couldn't outrageously high as you are living in a farm, your tomato should be much cheaper than the markets in the city.
Blue Gem may be more expensive, but let talk about it when we mine the blue gem coal.
Hopefully, you say this post makes total sense.
