How Much Is a Gold Bar Worth?
The value of a gold bar depends entirely on its weight and the current XAU/USD spot price. A standard 1 troy ounce gold bar — the most commonly traded retail size — is worth the live spot price shown on the live gold rates page. At the current spot rate, that is approximately $4,162 USD in melt value.
The price table above shows the melt value — pure gold content × spot price — for every standard bar size from 1 gram to the 400-ounce London Good Delivery bar. When you buy from a dealer, expect to pay 1–3% above melt value for common sizes (1 oz, 100g, 1 kg from major refiners like PAMP Suisse or Valcambi). Smaller bars (1g, 5g, 10g) carry higher premiums of 5–15% due to manufacturing cost relative to gold content.
Gold Bar Weights Explained
Gold bars come in two measurement systems: the metric system (grams and kilograms) used globally for retail investment bars, and the troy ounce system used for the wholesale interbank market. The key weights to know:
| Bar Name | Grams | Troy Oz | Typical Refiners |
|---|---|---|---|
| 1 gram bar | 1g | 0.032 oz | PAMP Suisse, Perth Mint |
| 10 gram bar | 10g | 0.321 oz | Valcambi, Argor-Heraeus |
| 1 troy oz bar | 31.1g | 1.000 oz | PAMP, Credit Suisse, US Mint |
| 100 gram bar | 100g | 3.215 oz | Valcambi, PAMP, Perth Mint |
| 1 kilogram bar | 1,000g | 32.15 oz | All major refiners |
| 400 oz bar (LGD) | 12,441g | 400 oz | LBMA-approved refiners only |

London Good Delivery Bar — The Wholesale Standard
The London Good Delivery (LGD) bar is the benchmark for central bank and institutional gold. Set by the London Bullion Market Association (LBMA), an LGD bar must weigh between 350 and 430 troy ounces (typically ~400 oz, 12.4 kg) and have a minimum fineness of 99.5% (995). Each bar carries the refiner mark, serial number, year of manufacture, and fineness stamp.
At the current spot price, a single LGD bar is worth approximately $1.66 million USD in melt value. Central banks hold gold reserves almost entirely in LGD form — stored at the Bank of England, Federal Reserve Bank of New York, Banque de France, and other official depositories. Retail investors buy smaller bars (1g to 1 kg) available at far lower premiums from licensed bullion dealers.
For long-term gold price performance context, see the 55-year gold price history — multiply any historical XAU/USD price by the bar weight in troy ounces for the bar value at that point in time.
Frequently Asked Questions
How is gold bar price calculated?
Gold bar price = bar weight in troy ounces × XAU/USD spot price. Example: 1 oz bar at $3,300/oz spot = $3,300 melt value. Dealers add a premium (1–15% depending on bar size) to cover manufacturing, handling, and margin. Use the live table above for current melt values for all bar sizes.
What is the cheapest way to buy gold bars?
Larger bars have lower premiums per ounce than smaller bars. A 1 kg bar from a major refiner typically costs 1–2% above spot; a 1g bar may carry a 10–15% premium. APMEX, JM Bullion, and SD Bullion (US) and the Perth Mint, Royal Mint, and Coininvest (international) are reputable dealers. Always compare total price per gram, not just listed premium.
How do I verify a gold bar is genuine?
Reputable bars carry the refiner stamp, fineness mark (e.g., 999.9), serial number, and weight. Assay-carded bars (sealed with certificate) from PAMP Suisse, Valcambi, or Argor-Heraeus offer the highest verification. XRF testers, ultrasound, and acid tests can verify purity. Buy only from LBMA-listed refiners or trusted national mints.
Can I sell a gold bar back for the full price?
Dealers buy back at 1–5% below spot, depending on the bar brand and market conditions. A premium-brand 1 oz PAMP Suisse bar will get a better buyback rate than a generic bar. Refiners, bullion banks, and pawn shops all offer buyback. The live melt value shown above is the ceiling for private-party sales.
