Scrap gold value = weight in grams × purity fraction × spot price per gram. For example, a 10 g 18K piece (75% pure) with gold at $90/g = 10 × 0.75 × $90 = $675 melt value. Dealers typically pay 80–95% of that figure.
Most reputable gold buyers pay 80–95% of melt value. Pawnshops typically offer 60–75%. Specialist refiners and online gold buyers may pay 90–98%. Use the buyback slider above to model any scenario.
Look for a hallmark stamp — usually a number like 750 (18K), 917 (22K), 585 (14K), 375 (9K). North American pieces are often stamped with the karat directly: 18K, 14K, 10K. If there's no stamp, a jeweler can test purity with nitric acid or an XRF analyzer.
24K (99.9% pure) has the highest scrap value per gram because it contains the most pure gold. 22K is 91.67% pure and is worth about 8.3% less per gram than 24K. For a given weight, higher karat always means higher scrap value.
