Coal
“Hmm a non-renewable energy source!”
About this item
Coal can be mined at level 30 Mining providing 50 Mining experience. After coal rocks are mined, it will take 30 seconds until it reappears. Coal is required to smelt all ores above iron (other than gold, silver, lead, and nickel), in increasing amounts. Members can store 27 pieces of coal in one inventory space by using a coal bag, obtained from Prospector Percy's Nugget Shop for 100 golden nuggets at Motherlode Mine.

Its high alch value of 27 does not cover the 154 nature rune it would burn, so alching is a loss before the item itself is counted.

Measured with medians rather than averages, because one spike — an update, a streamer, a brief squeeze — drags an average around for weeks afterwards and makes everything since look ordinary.
