100 g minted gold bar Umicore — fineness 999.9/1000, LBMA Good Delivery, CertiCard with serial number
100 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 100 g format is the largest denomination in the Umicore minted bar series — its weight corresponds to approximately 3.215 troy ounces. Dimensions of approximately 50 × 28 × 3.5 mm provide the solid physical presence typical of the premium segment. The percentage premium over spot reaches its minimum across the entire Umicore retail series at this level — the lowest of all minted denominations. For buyers who prioritise maximum metal content at the lowest possible markup, 100 g is the optimal choice. The bar retains all the advantages of the minted format: mirror-like surface, precise dimensions and CertiCard packaging with serial number.

Why the 100 g minted gold bar from Umicore
The 100 g denomination marks the top of the Umicore minted retail series — the percentage premium over spot is at its lowest here, translating into the highest cost efficiency per gram of metal. At approximately 3.215 troy ounces, a single 100 g bar replaces over three ounce bars — at a lower total cost and fewer positions to store. Above 100 g most refineries switch to the cast format, yet Umicore maintains the minting technique at this weight, preserving the mirror surface, precise dimensions and CertiCard packaging. The CertiCard with serial number eliminates the need for additional verification at resale.
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. At 100 g the minting process requires the highest press forces in the entire retail series — deep relief, sharp detail, mirror finish.
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 100 g denomination closes the series at the top — the heaviest minted bar in the Umicore range, corresponding to over three troy ounces. As the largest retail format it offers the lowest percentage premium and the highest concentration of metal in a single position. Above 100 g most refineries switch to the cast format, yet Umicore maintains the minting technique at this weight.
What to look for when buying a 100 g Umicore bar
CertiCard integrity; fineness and weight — 100.00 g / 999.9; LBMA accreditation; minted vs cast — the 100 g Umicore bar retains the minting technique (mirror surface, precise edges, CertiCard), distinguishing it from the cast formats most refineries use at this denomination.
