Grey hat

The Grey hat is a members-only Old School RuneScape item — “A silly pointed hat.”. Its Grand Exchange buy limit is 150 per 4 hours. Right now it buys at 939 gp and sells at 996 gp — a net margin of 38 gp (4.0% ROI) after the 2% Grand Exchange tax of 19 gp. High alchemy yields 300 gp.

To flip it, place a buy offer near 939 gp and a sell offer near 996 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
