A standard gold brick — a 400-troy-ounce Good Delivery bar — is worth about $1,614,440 at today’s gold price. That is 400 troy ounces of .995 fine gold, the bar central banks trade.
The number moves with the gold price, so the honest answer is a formula, not a fixed figure: 400 times the current spot price per troy ounce. At the gold spot used for this page, $4,036.10 per troy ounce on November 11, 2026, the math lands at $1,614,440. Everything below — the smaller bars, the premiums, the question of whether you can actually buy one — follows from that one multiplication.
What Counts as a Gold Brick?
There is no official product called a “gold brick.” The term people mean is the Good Delivery bar: the standard bar of the London Bullion Market Association (LBMA), the form in which central banks, refiners and large dealers settle gold. A Good Delivery bar weighs between 350 and 430 troy ounces — the 400-ounce figure is the standard, not a rule — and must be at least .995 fine, meaning 99.5% pure gold. The typical bar is about 7 inches long, 3⅝ inches wide and 1¾ inches tall, and weighs about 12.4 kilograms (27.4 pounds). Pick one up in a film and the actor is pretending: 27 pounds of dense metal does not lift like a loaf of bread.
Smaller bars get called bricks too, especially the 1-kilo bar, but the trade reserves “gold brick” for the 400-ounce Good Delivery size. If a seller offers you a “gold brick” that weighs an ounce or two, it is a retail bar with a dramatic name, not the institutional standard — and it is priced like a retail bar, with a premium over melt.
How Much Is a Gold Brick Worth by Size?
Every figure in this table is the melt value — the metal content times today’s spot price — not a retail price. Retail bars always cost more than melt; the gap is the premium, covered below.
| Bar | Weight | Melt value |
|---|---|---|
| Good Delivery “gold brick” | 400 troy oz | $1,614,440 |
| 1-kilo bar | 32.1507 troy oz | $129,763 |
| 100-oz bar | 100 troy oz | $403,610 |
| 10-oz bar | 10 troy oz | $40,361 |
| 1-oz bar | 1 troy oz | $4,036.10 |
| 1-gram bar | 1 gram | $129.76 |
Melt values from Data by Bullion Price Check, data as of November 11, 2026 (gold spot $4,036.10 per troy ounce). Melt is metal value only; retail prices sit above melt and exclude shipping and tax. For the live price and the per-gram breakdown, see gold price today and our gold price per gram guide.
The range matters too: because Good Delivery bars run 350 to 430 ounces, a light bar melts near $1,412,635 and a heavy one near $1,735,523 at the same spot price. Dealers price each bar on its exact stamped weight, never on the round 400-ounce figure.
Why a Gold Brick Costs More Than Melt
The melt value is the floor, not the price. A Good Delivery bar bought on the wholesale market trades very close to spot — the premium is small because the buyer is an institution moving millions — but a retail buyer pays more at every step: fabrication, assay, the dealer’s margin, insured shipping, and, for a bar this size, secure storage. The premium shrinks as the bar grows: a 1-ounce bar carries a far larger percentage premium than a 400-ounce bar, which is why the per-ounce cost falls with size.
Our own catalog shows the pattern on the day this page was written (November 11, 2026): a 1 oz Gold Eagle lists at $4,296.41 against $4,036.10 of melt, about 6.4% over spot, while a 1/2 oz gold bar lists at $2,095.94 against $2,018.05 of melt, about 3.9% over. The same metal, the same day — the smaller piece carries the bigger percentage premium. A Good Delivery brick sits at the far end of that curve, where the premium is thinnest.
Can You Buy a Gold Brick?
Yes, but not the way you buy a coin. Good Delivery bars trade between refiners, banks and large dealers in minimums that start in the hundreds of thousands of dollars, and most buyers never take delivery — the bar sits in an allocated vault and ownership changes on paper. A private buyer who wants one needs a dealer who handles Good Delivery, a wire transfer, and a storage plan: a $1.6 million bar does not belong in a home safe, and insuring it costs real money every year.
For most buyers, the practical version of the same metal is the retail bar. A 1-ounce bar holds the same .9999 fine gold at a premium a normal budget can absorb, and it can be sold back anywhere that buys gold. Our best 1 oz gold bars guide compares the brands by premium, and the gold and silver bar sizes chart lays out every weight from 1 gram to 1 kilo with its melt value. If you are deciding between a bar and a coin, the 1 oz gold bar dimensions page shows how the common bars actually measure up.
The retail end of the same metal: a 1/2 oz Gold Bar – Brand Varies .9999 (Carded) at $2,095.94, or the classic 1 oz Gold Eagle – BU (Year Varies) at $4,296.41 — both in stock on the day this page was written, November 11, 2026. Prices track spot and move daily; the melt figures above are the metal value, not the delivered price.
