It may be a little better in SW PA, but I have to say that although there is still some really good coal here around Frostburg, many small mining operators will sell stuff that's far from great for "housecoal". I'm 54, and it seems to me that for the past 20 years or so, it's really hit or miss. Oldtimers always said that if it's shiney, even a little oily looking, it's good big vein.
I hand fired a small bit boiler in my home for 5 years or so prior to fitting an old IronFiremen. Good big vein was a pleasure to use when I hand fired. The good big vein is often saved to be mixed down to enable them to sell the dirtier burning seams to the plants. Fwiw, getting stoker coal that had good heat and would clinker well was even a little more challenging. "They" often are getting rid of coal that they can't sell to the powerplants.
That said, my Kaa-2 costs me more per winter, and is worth every extra penny spent.
