How to flip the Coal
The Coal is a free-to-play Old School RuneScape item — “Hmm a non-renewable energy source!”. Its Grand Exchange buy limit is 13,000 per 4 hours. Right now it buys at 148 gp and sells at 150 gp — a net margin of -1 gp (-0.7% ROI) after the 2% Grand Exchange tax of 3 gp. High alchemy yields 27 gp.
To flip it, place a buy offer near 148 gp and a sell offer near 150 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
