How to flip the Muddy key
The Muddy key is a free-to-play Old School RuneScape item — “It looks like the key to a chest.”. Its Grand Exchange buy limit is 11,000 per 4 hours. Right now it buys at 6,647 gp and sells at 7,000 gp — a net margin of 213 gp (3.2% ROI) after the 2% Grand Exchange tax of 140 gp. High alchemy yields 48 gp.
To flip it, place a buy offer near 6,647 gp and a sell offer near 7,000 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
