Where the numbers come from and how we turn them into karat, coin and scrap values.
The headline price is the spot price of one troy ounce (31.1035 g) of pure metal in US dollars, taken from public market data feeds and refreshed about every 60 seconds. Day highs, lows and the 52-week range come from the COMEX futures market, adjusted to the spot level. Historical gold prices come from the World Gold Council's daily series; silver, platinum and palladium history uses COMEX settlement prices.
Gold trades almost around the clock from Sunday 6pm to Friday 5pm Eastern Time. Outside those hours we show the last traded price.
A karat price is the spot price per gram multiplied by the gold content: 24K 99.9%, 22K 91.67%, 18K 75%, 14K 58.5% and 10K 41.7%. One pennyweight (dwt) is 1.555 grams.
Melt value is what the pure metal in an item is worth at spot. Buyers need to refine scrap and make a margin, so our “expected offer” range of 70–90% of melt reflects what established US gold buyers typically pay. Pawn shops often pay less; dealers sell coins and bars above spot.
