What is 950 worth by weight?

Every gram of a piece stamped 950 holds 0.95 g of fine platinum, if the stamp is accurate. Multiply that by the spot price of platinum to get the melt value. It is the floor, what the metal is worth if melted, not what a buyer will pay and not an appraisal.

Example, clearly not live: 10 g at the example price of $1,555.00 per troy ounce (snapshot of 2026-11-10) is $474.95. The working: 10 g → 950 / 1000 → 10 g × 0.95 → 1555 USD/ozt ÷ 31.1034768 g/ozt → 9.5 g × 49.9944 USD/g.
