You can break coal in two ways. Either by crushing it which requires considerable force or smashing it off something like other coal. For example if you get bulk delivery as the coal is flowing into the bin it's smashing off the other pieces already in the bin and creates some amount fines. It's not a large amount but every time you move it you create some amount of fines. When I say move that would exclude moving bags around. In my chute example it's the speed of the coal hitting the other pieces that is the important factor there.
Other than a bag of coal getting run over with something improper handling wouldn't be factor. The bag would probably be destroyed long before the coal would get to a really bad condition. It was most likely packed that way.
..Having said that I believe we've covered just about every supplier in the "XXXX Companies coal sucks". The fact is quality will vary from just about any supplier. In a sense it's like playing the lottery but in this lottery you're going to have many winners and just a few losers.
The best thing to do if possible is get bulk in the summer and you greatly increase your chances of getting a very clean, consistent and quality product.
