1 g Gold Bars

How big a 1 g gold bar actually is

Because the bar is so thin, it is almost always sold sealed in a blister card rather than loose: the card makes it handleable and carries the assay data. Argor-Heraeus states its blister format outright — 85 × 55 mm, the dimensions of a bank card. The figures below are published producer specifications and cover refineries whose bars may not all be in stock here at once.

Refiner or standard	Dimensions	Form	Packaging
Argor-Heraeus	15.0 × 8.7 × 0.5 mm	minted	blister + assay card
Umicore	15 × 8.5 × approx. 0.5 mm	minted	sealed blister
Metalor	8.7 × 15 mm	minted	blister, six-digit serial number

Valcambi and PAMP do not publish specification tables for their single bars. Both ship the 1 g bar in a sealed assay card; PAMP calls its version CertiPAMP and prints a certificate number on it.

Why the premium is highest here

A gram of gold is about 0.052 cm3 of metal — a volume the rolling mill, the press, the serial-number die and the sealing line all handle at exactly the same cost as a hundred times more. That fixed cost is what you are looking at when you compare the price per gram of a 1 g bar against a 100 g bar.

It is not an argument against the format — it is the price of divisibility. A 1 g bar is the smallest unit you can hand over, store separately or sell on its own.

The CombiBar alternative

Valcambi also makes the 1 g bar as part of a scored sheet: 50 or 100 individual gram bars in one card that you break apart by hand. The 100-piece version is 74 × 105 × 0.8 mm — the exact footprint of a DIN A7 card. It gives you the same divisibility at a lower premium per gram than buying a hundred separate bars, at the cost of buying the whole sheet at once.

Refiners in this weight

The listing covers Valcambi, PAMP, Argor-Heraeus, C.Hafner, Umicore, Perth Mint and the Royal Mint, plus the Argor-Heraeus Kinebar with its integrated KINEGRAM hologram. Valcambi, PAMP, Argor-Heraeus, C.Hafner, Umicore and the Perth Mint all appear on the LBMA Good Delivery list for gold. The Royal Mint does not — it is a mint rather than an accredited refinery. The accreditation belongs to the refinery and its assay process, not to an individual bar, and the LBMA issues no certificate to a retail buyer. Live prices track the market on our gold price page.

Questions buyers ask about this weight

How much is a 1 g gold bar worth?

The gold price for one gram plus the premium on that specific bar. Because the fabrication cost is fixed and the metal content is tiny, the premium is a much larger share of the total here than in any heavier format.

How big is a 1 g gold bar?

15 mm long, about 8.5 to 8.7 mm wide and roughly half a millimetre thick, according to the specifications published by Argor-Heraeus, Umicore and Metalor.

Should I open the blister?

There is no need to. The sealed card carries the weight, the fineness and, on most brands, a serial number, and an unopened card is what a buyer will expect to see if you resell. The metal is unaffected either way, but the packaging is part of what you are holding.

Is a CombiBar the same thing?

Not quite. A CombiBar is a single sheet scored into 1 g segments that snap apart. You get the same gram-by-gram divisibility, usually at a lower premium per gram, but you buy the whole sheet in one transaction.

Will you buy a 1 g bar back?

Yes. Small bars are quoted the same way as large ones, against the current market price. Details are on the buyback page.
