Silver locks

The Silver locks is a members-only Old School RuneScape item — “Perhaps someone can do something with this.”. Its Grand Exchange buy limit is 8 per 4 hours. Right now it buys at 10,500 gp and sells at 10,000 gp — a net margin of -700 gp (-6.7% ROI) after the 2% Grand Exchange tax of 200 gp. High alchemy yields 11,520 gp.

To flip it, place a buy offer near 10,500 gp and a sell offer near 10,000 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
