Mining coal is worthless. Only I buy for 200 each, and that is for 4k or more. 99 percent of the people buy for 150 each. It is not really worth mining for money until you are able to mine addy or rune ore. Which is about 10k per ore. How do I make money? When I was a lower level player, I would buy 4k coal, and 2k iron. I would make steel bars (2k), and sell for 600 each. I got about 1.5 mil. That is a 1mil profit every time. I can smelt 2k steel bars in a week over the summer. Now, I mine addy ore, and buy coal. I then sell the addy bars. Another way to make good money, is merchanting. It is really worth it. Buy a huge number of imporant materials ( coal and wood, being reaaly good. flax is also good) for a really low price. And sell them for at least 50-100 gp higher. you get lots of money ( Best merchants get around 500k profit for each session of mercahnting) and the best part is, all of your leveling up would go towards your combat. So you don't need to worry about all time it takes for geting your smithing to 99. I used to do merchanting for full rune sets. Buying for 184 sellling for 200. I did this until I needed to make more millions faster for all the dragon items. Hope this helps you.
