10K Scrap Gold Calculator
41.7% Pure · Common lower-karat US jewelry alloy
Calculate the melt value of gold coins including Sovereigns, American Eagles, Krugerrands, and Maple Leafs using live spot prices.
Melt value only. A collectible or numismatic coin may be worth more than its metal value.
See what buyers actually pay — after deductions →The Gold Coin Value Calculator estimates a coin's gold melt value from its gold content and current gold price.
Calculate the melt value of gold coins including Sovereigns, American Eagles, Krugerrands, and Maple Leafs using live spot prices.
The calculator follows this formula so the estimate stays tied to weight, purity, and the current gold spot price:
V is estimated melt value, AGW is actual gold weight in troy ounces, and P is the gold spot price per troy ounce.
Calculations use standard weight and purity formulas with live market spot prices. See our Calculation & Editorial Methodology for complete formula steps and limitation disclosures.
Real-world buyback spreads for bullion and scrap gold coins
Coin offers depend on whether the piece is being bought for bullion resale, collectible value, or melt. Compare dealer buyback quotes with melt value before treating a coin as scrap.

Three steps — check coin specifications, verify purity, calculate melt value
Many well-known bullion coins use 22K alloy for durability while still carrying a stated fine-gold content. Check the mint specification for the exact gross weight and fine-gold weight of your specific coin.
Many modern bullion coins are struck in very high fineness such as 999 or 999.9 gold. Use the coin's listed purity and weight instead of assuming every piece follows the same standard.
Pre-1933 US $20 Liberty/St. Gaudens double eagles weigh 33.436 grams in 90% gold (21.6K), containing 0.9675 troy oz of pure gold. They frequently trade above melt value due to collector demand.
Important differences between scrap melt value and bullion premiums
This calculator estimates metal melt value from the coin's weight and purity. Actual sale price can be higher or lower depending on authenticity, demand, condition, and whether the buyer is paying for bullion, collectible value, or scrap.
Intact bullion coins are often evaluated differently from generic scrap, so it is worth checking coin-dealer or bullion-buyer quotes before accepting a melt-based offer. Damaged, holed, mounted, or altered coins are more likely to be priced primarily for metal content.
Gold coins mounted in pendant bezels often have solder or rim damage. When calculating scrap value, weigh the coin and bezel separately if they are different karats (e.g. 22K coin in 14K bezel).
Refineries test gold coins using XRF spectrometers, specific gravity testing, or acoustic resonance to confirm purity before smelting.

Estimate the contained gold value of jewelry, coins, bullion, and other items based on weight, karat purity, and the current spot price.
Multiply the coin's gross weight by its gold purity fraction, convert the fine-gold weight to troy ounces, and multiply by the live spot price. That gives a melt-value estimate before any buyer spread or collectible premium.
A 1 oz Eagle contains 1 troy oz of fine 24K gold within a 33.93g 22K alloy coin (alloyed with silver and copper).
Contains 1 troy oz of pure gold in a 22K alloy (33.93g gross); melt value equals 1 × current spot price per troy oz.
Use the Sovereign's published gross weight and purity to calculate its fine-gold content, then multiply that fine-gold amount by the live spot price. The exact melt value changes whenever the market price changes.
Compare a coin or bullion dealer's net quote with a scrap buyer's net quote before selling. Published specifications can establish the metal-value baseline, while condition, authenticity, demand, and collectible value may affect a specialist quote.
Canadian Maple Leaf (99.99%), Austrian Philharmonic (99.99%), Australian Kangaroo (99.99%), and Chinese Panda (99.9%).
Damage can reduce or eliminate some collectible premium, depending on the coin and market. Its metal-value baseline still depends on the remaining verified fine-gold content and current spot price.
