50 g Gold Bars
Number of products: 17Fifty grams is where casting becomes a mainstream option. The Perth Mint pours as low as one ounce, but from 50 g upwards Argor-Heraeus and Valcambi both run a cast line alongside the minted one — so this is the beginning of the overlap that ends at 100 g. Umicore starts pouring only at 100 g.
The minted bar measures 49.7 × 28.5 × 2.0 mm at Argor-Heraeus and 46 × 26 mm at around 2.3 mm at Umicore: still card-sized, and now with noticeable weight.
How big a 50 g gold bar actually is
The face has stopped growing much — Argor-Heraeus uses the same 49.7 × 28.5 mm outline for 50 g and 100 g — and the thickness has started doing the work instead. Figures are published producer specifications rather than current stock.
| Refiner or standard | Dimensions | Form | Packaging |
|---|---|---|---|
| Argor-Heraeus | 49.7 × 28.5 × 2.0 mm | minted | blister 85 × 55 mm + assay card |
| Umicore | 46 × 26 × approx. 2.3 mm | minted | sealed blister |
| Metalor | 25.7 × 44.2 mm | minted | blister, six-digit serial, DataMatrix code |
Argor-Heraeus shares the 49.7 × 28.5 mm footprint between its 50 g and 100 g minted bars, doubling the thickness from 2.0 mm to 3.9 mm. Side by side they are the same card; stacked, one is twice the other.
Where the premium curve flattens
From 50 g upwards the fabrication cost has been diluted to the point where moving further up the range buys progressively less. The gap in premium per gram between 50 g and 100 g is small; between 100 g and one kilo, smaller still. Below 50 g each step down costs noticeably more per gram.
That makes 50 g the dividing line in this range: the lightest weight at which Argor-Heraeus and Valcambi offer a cast bar, and the last at which the sealed card is still the default format.
Refiners in this weight
Valcambi, PAMP, Argor-Heraeus, C.Hafner, Umicore, Perth Mint, the Royal Mint, Rand Refinery, Münze Österreich and Istanbul Gold Refinery, plus the Argor-Heraeus Kinebar. Valcambi, PAMP, Argor-Heraeus, C.Hafner, Umicore, the Perth Mint, Rand Refinery and Istanbul Gold Refinery all appear on the LBMA Good Delivery list for gold. The Royal Mint and Münze Österreich do not appear on it — they are mints rather than accredited refineries, and Münze Österreich states outright that its bars are produced by Argor-Heraeus or PAMP. 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
Fifty grams of gold at the market price, plus the refinery premium, plus our margin. Fifty grams is 1.608 troy ounces, so an ounce-based quote needs converting before you compare. Live prices on the gold price page.
Questions buyers ask about this weight
How much is a 50 g gold bar worth?
Fifty times the gold price per gram plus the premium. In ounce terms that is 1.608 troy ounces, which is worth checking if you are comparing against an ounce quote.
How big is a 50 g gold bar?
49.7 × 28.5 × 2.0 mm at Argor-Heraeus, 46 × 26 mm at roughly 2.3 mm thick at Umicore, 25.7 × 44.2 mm at Metalor.
Is a 50 g bar minted or cast?
Usually minted, but this is the weight where cast versions become common: Argor-Heraeus and Valcambi both list 50 g in their cast ranges as well as their minted ones. Umicore starts casting at 100 g, the Perth Mint already at one ounce.
Why does it look like the 100 g bar?
At Argor-Heraeus it is the same 49.7 × 28.5 mm face. The difference is thickness: 2.0 mm against 3.9 mm. The stamp on the bar is the reliable way to tell them apart.
Do you buy 50 g bars back?
Yes, quoted against the market price on the day. At 50 g the minted and cast versions are quoted separately, because the premium on them differs. See the buyback page.
