1 oz minted gold bar Umicore — fineness 999.9/1000, LBMA Good Delivery, CertiCard with serial number
1 oz (31.1035 g) of gold at 999.9/1000 fineness (.9999) in minted bar form from Umicore — a Belgian materials technology group headquartered in Brussels, operating since 1805 and holding LBMA Good Delivery accreditation. Each bar carries an individual serial number and is delivered in a hermetically sealed CertiCard.
The 1 oz format (one troy ounce — 31.1035 g) is the international benchmark unit for bullion gold, used as the base unit on commodity exchanges (LBMA, COMEX) and in spot quotations. Dimensions of approximately 41 × 24 × 1.5 mm place this bar in the medium-large minted segment, where the percentage premium over spot is low — comparable with 50 g and markedly lower than gram formats (1-20 g). For buyers oriented towards international price benchmarks, the 1 oz format provides direct comparability with market quotations without gram-to-ounce conversion.

Why the 1 oz minted gold bar from Umicore
The troy ounce is the global unit of account for the gold market — the XAU/USD and XAU/EUR spot price and COMEX futures contracts are all quoted in troy ounces. A 1 oz bar from Umicore provides direct access to this benchmark without gram-to-ounce conversion. The percentage premium over spot at the ounce level is low — comparable with 50 g and markedly more favourable than the 1-20 g denominations. The 1 oz format is also the most popular denomination among bullion coins (Krugerrand, Maple Leaf, Wiener Philharmoniker), which means the highest market liquidity at resale. The CertiCard with serial number eliminates the need for additional verification.
Umicore — over two centuries of Belgian metal refining tradition
The history of Umicore dates back to 1805. As Union Minière du Haut Katanga, the firm became a leading European player in metal refining. In 2001 it adopted the name Umicore. The Hoboken plant (Antwerp) is one of the world's largest precious metals recovery facilities — processing over 200 material types in a closed loop. Listed on Euronext Brussels (UMI), over 11,000 employees, 31 countries, 3+ bln EUR revenue.
Production technology — minting from the "Finesse" series
Gold refined to 999.9/1000 is cast into strip, rolled, cut and struck under high pressure. Obverse: Umicore logo, "999.9", nominal weight, individual serial number. The finished bar is hermetically sealed in a CertiCard — credit-card-format plastic card with the manufacturer's certificate.
Denominations and weights in the Umicore range
Denominations from 1 g to 100 g plus 1 oz (31.1 g). At GoldInvest24: 1 g, 2.5 g, 5 g, 10 g, 20 g, 50 g, 1 oz, 100 g. The 1 oz format is the only denomination in the series expressed in troy ounces — 31.1035 g sits between 20 g and 50 g by weight, but serves as the international price benchmark. Directly comparable with spot prices, futures contracts and bullion coin quotations without additional conversion.
What to look for when buying a 1 oz Umicore bar
CertiCard integrity; fineness and weight — 31.1035 g (1 oz) / 999.9; LBMA accreditation; comparison with 1 oz coins — the Umicore minted bar typically carries a lower premium than most 1 oz bullion coins at identical metal content.
