Well I just found a local smith that's actually down the road from me. He sells a 50 lb sack for $20 which is a great price from what I've seen online. He also has taught at a local college in metal work. So I'm gonna reach out to him because he's now doing private lessons for new blacksmiths. I put the specs he listed below for the coal because it doesn't mean much to me. Thanks for all the advice.
