5 g Gold Bars
Number of products: 24At 5 g a gold bar stops being a token and starts being a solid, handleable object: 23.0 × 14.0 × 0.9 mm at Argor-Heraeus, 24 × 14 mm at Umicore, 15.5 × 25.5 mm at Metalor. It is still under a millimetre thick, and still sold sealed in a card.
This is the weight where the premium per gram has fallen noticeably from the 1 g and 2 g formats without the outlay yet becoming substantial — which is why it is one of the most heavily stocked weights in the range.
How big a 5 g gold bar actually is
Five grams of gold occupies roughly a quarter of a cubic centimetre. Every refinery solves the same problem differently — some go wider, some go longer — but all stay under a millimetre of thickness. The table gives published producer specifications, not current stock.
| Refiner or standard | Dimensions | Form | Packaging |
|---|---|---|---|
| Argor-Heraeus | 23.0 × 14.0 × 0.9 mm | minted | blister + assay card |
| Umicore | 24 × 14 × approx. 0.9 mm | minted | sealed blister |
| Metalor | 15.5 × 25.5 mm | minted | blister, six-digit serial number |
Argor-Heraeus and Umicore land within a millimetre of each other on the face — 23.0 × 14.0 mm against 24 × 14 mm — and both stop at 0.9 mm thick, which is the constraint that really shapes a bar this light.
Where 5 g sits in the range
The premium curve across the bar range is steep at the bottom and flat at the top. Between 1 g and 5 g it falls sharply, because the same fabrication work is now spread over five times the metal. Between 50 g and 1 kg it barely moves. Five grams is on the steep part but past the worst of it.
In practice buyers use this weight for two things: adding to a holding gradually rather than committing to a one-ounce bar in one go, and holding gold in units small enough to sell piece by piece.
Refiners in this weight
The listing covers Valcambi, PAMP, Argor-Heraeus, C.Hafner, Umicore, Perth Mint, the Royal Mint and Münze Österreich, along with the Argor-Heraeus Kinebar. Münze Österreich does not run its own bar line: the Austrian Mint states that its bars are produced by Argor-Heraeus or PAMP. It publishes no dimensions of its own.
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 appear on it — 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.
What you actually pay
Metal value for 5 g at the current market price, plus the refinery premium, plus our margin. The metal component moves continuously during trading hours; the premium does not. Live figures are on our gold price page.
Questions buyers ask about this weight
How much is a 5 g gold bar worth?
Five times the gold price per gram, plus the premium on that bar. The premium is a smaller share of the total than on a 1 g or 2 g bar, and a larger share than on a 100 g bar.
How big is a 5 g gold bar?
23.0 × 14.0 × 0.9 mm at Argor-Heraeus, 24 × 14 mm and about 0.9 mm thick at Umicore, 15.5 × 25.5 mm at Metalor. All three are under a millimetre thick.
Is a 5 g bar minted or cast?
Minted. Casting only becomes standard from 50 g upwards, and at this weight every refinery presses the bar from rolled strip.
What is in the packaging?
The bar is sealed into a blister that also serves as the assay card. It states the weight and the fineness, and on most brands carries a serial number that matches the bar.
Do you buy 5 g bars back?
Yes, at a rate quoted against the current market price. 5 g is one of the deepest listings we hold, which keeps the resale spread on it tight. The buyback page explains how.
