Melt value of the metal alone. Weigh the whole piece and subtract stones and other materials first.
This is the melt value: what the gold in coin gold 90% is worth at today's spot price and nothing more. A gram of coin gold 90% contains 90% pure gold, so its melt value is 90% of the gold spot price per gram. It ignores craftsmanship, brand, stones and any collector value.
Buyers pay less than melt. Scrap buyers, pawn shops and refiners deduct refining costs and their margin, so an offer is usually a percentage of the figure above and varies with quantity, purity and the buyer. Use this page to know what the metal is worth before you accept one.
