BULLION COIN MELT VALUE + PREMIUM
Calculate the gold inside a coin before judging its market price
Choose a common bullion coin with an official-mint specification or enter a custom gross weight and fineness. GoldObserve applies the current source-labelled gold price to the coin's fine-gold content, totals multiple coins, models a dealer payout and separates purchase premium or offer discount from raw metal value.

Measure premium, discount and break-even spot
Enter the purchase price or buyer offer for one coin. Negative premium means the entered price is below calculated melt value.

Preset specifications are product references from the named official mints. Verify the exact year, variant and authenticity of the coin before a transaction. One troy ounce equals 31.1034768 grams.
How gold coin melt value is calculated
Melt value measures contained gold only. For a preset coin, the calculator uses the official fine-gold content rather than multiplying a rounded gross weight by a rounded fineness. For a custom coin, it converts gross weight to grams, applies fineness and divides pure-gold grams by 31.1034768.
Identify the exact coinSeries, size, year and variant can change specifications. Match the coin to an official product reference.
Find fine-gold contentUse the stated troy ounces of fine gold, or calculate gross grams × fineness ÷ 1,000.
Calculate melt valueFine-gold troy ounces × quantity × gold spot price per troy ounce.
Compare the transaction separatelyEntered price − melt value produces premium or discount; it does not determine collectible value.
Why gross coin weight and fine-gold weight can differ
Some bullion coins contain alloy metals for hardness. A one-ounce American Gold Eagle contains one troy ounce of gold but has a higher gross weight because its 22-karat composition also includes silver and copper. A fine-gold coin can have gross and gold weights that are nearly the same. The labeled fine-gold content is the relevant input for melt value.
Specifications are linked to official mint sources
Each preset exposes its source in the calculator and CSV. Current reference families include the United States Mint American Gold Eagle, Royal Canadian Mint Gold Maple Leaf, The Royal Mint Britannia, Perth Mint Kangaroo and Austrian Mint Philharmonic.
Official specifications do not authenticate the coin in hand. Counterfeits, damaged pieces, nonstandard editions and jewelry-mounted coins require additional examination. Verify the exact product before relying on a preset for a material transaction.
Melt value, face value and numismatic value are not interchangeable
Face value is the legal-tender denomination printed on a coin. Melt value is the market reference for its contained gold. A transaction price may also reflect fabrication, distribution, dealer spread, scarcity, condition, grade, packaging and collector demand. The calculator reports these categories separately and does not infer a numismatic appraisal.
Using the premium and break-even fields
Enter a per-coin purchase price to calculate the amount and percentage above or below melt. Break-even spot is the gold price at which that entered coin price would equal its melt value, before selling costs, tax or time value. Entering a buyer offer uses the same arithmetic but should not be interpreted as a guaranteed bid.
Frequently asked questions
Is a one-ounce Gold Eagle one troy ounce in total weight?
No. It contains one troy ounce of fine gold but weighs more in total because the coin is 22-karat alloy. Use fine-gold content for melt value.
Does melt value include the coin's collector premium?
No. Melt value includes gold only. The optional price field measures an entered premium or discount separately.
Can I calculate an old or unlisted gold coin?
Yes. Choose custom specifications and enter gross weight plus fineness from a reliable reference. The tool then calculates fine-gold content.
Why can an entered buyer offer be below melt value?
A buyer may account for verification, inventory, hedging, processing and resale costs. The calculator reports the difference but does not label the offer fair or unfair.
Does the tool authenticate coins?
No. Dimensions, weight, security features and professional testing may be needed. A matching calculation is not proof of authenticity.
