Silver dust

The Silver dust is a members-only Old School RuneScape item — “It's ground up silver.”. Its Grand Exchange buy limit is 13,000 per 4 hours. Right now it buys at 904 gp and sells at 1,499 gp — a net margin of 566 gp (62.6% ROI) after the 2% Grand Exchange tax of 29 gp. High alchemy yields 120 gp.

To flip it, place a buy offer near 904 gp and a sell offer near 1,499 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
