100 g Minted Gold Bar Argor-Heraeus — 999.9/1000 fineness, LBMA Good Delivery, assay card with serial number
100 g of gold, 999.9/1000 fineness (.9999), in minted bar form from Argor-Heraeus SA — a Swiss refinery based in Mendrisio, Canton Ticino, founded in 1951 and LBMA Good Delivery accredited since 1961. Argor-Heraeus is part of Heraeus Holding GmbH — a German group with a precious metals processing tradition dating back to 1851. Each bar carries an individual serial number and is delivered in a blister with an assay card confirming weight, fineness, and authenticity.
The 100 g format is the largest denomination in the Argor-Heraeus minted series — a bar exceeding three troy ounces (3.21507 oz t) with dimensions of 31 × 54 × 3 mm. At this weight, the percentage premium over the spot price reaches its lowest value across the entire minted product range. The 100 g bar marks the point where per-gram acquisition costs come closest to wholesale pricing — the most cost-efficient denomination in the Argor-Heraeus minted series, chosen by buyers accumulating substantial bullion positions in single, compact units.

Why the 100 g Minted Gold Bar from Argor-Heraeus
The 100 g format is the most cost-efficient denomination in the entire Argor-Heraeus minted series — the percentage premium over the spot price reaches its minimum across all seven available formats. Argor-Heraeus SA processes over 400 tonnes of gold annually and is one of the few entities worldwide holding simultaneous LBMA Good Delivery accreditation for gold, silver, platinum, and palladium. The assay card with serial number eliminates the need for additional verification upon resale. The 100 g minted bar is the choice of buyers maximising the metal-to-unit ratio — over three troy ounces in a single format with dimensions close to a bank card, simplifying both storage and inventory management.
Argor-Heraeus SA — over seven decades of precious metal refining
The Argor-Heraeus SA refinery was founded in 1951 in Mendrisio, Canton Ticino, southern Switzerland. It initially operated as Argor SA, offering gold and silver refining for the Swiss banking sector. In 1999, a merger with the precious metals division of Heraeus Holding GmbH — a German industrial group with a tradition dating back to 1851 — created the present-day corporate structure. The company is part of the Heraeus group and ranks among the world's largest gold processors, with an annual refining capacity exceeding 400 tonnes.
Argor-Heraeus obtained LBMA Good Delivery accreditation for gold in 1961 — just a decade after its founding. The refinery also holds LBMA accreditations for silver, platinum, and palladium, as well as Responsible Jewellery Council (RJC) certification and compliance with the LBMA Responsible Gold Guidance. The product portfolio includes minted bars (1 g — 100 g), cast bars in larger formats, and the Kinebar series featuring a KineGram hologram as an additional anti-counterfeiting measure.
Minting technology — precision and production consistency
The Argor-Heraeus minted series comprises bars produced by precision die stamping from a gold strip of 999.9/1000 fineness. The process begins with casting gold refined to .9999 purity, which is then rolled into a thin strip of precisely controlled thickness. Blanks of target weight are cut from the strip, and each blank is stamped in a die to form a rectangular bar bearing the Argor-Heraeus logo, weight designation, fineness marking, and individual serial number.
The obverse features the characteristic smooth, mirror-like surface typical of the minting technique. Each bar is placed in a manufacturer's protective blister with an assay card. The blister protects the product from environmental contact and mechanical damage while allowing visual verification without opening the packaging. At 100 g, the minting technique delivers the same dimensional precision and surface quality as for smaller denominations — it is the largest format for which Argor-Heraeus employs the minted method.
Denominations in the Argor-Heraeus minted series
The minted series encompasses seven denominations: 1 g, 2 g, 5 g, 10 g, 20 g, 50 g, and 100 g. Each format is delivered in the same finish with serial number and assay card. The manufacturer also offers the parallel Kinebar line with KineGram hologram and cast bars from 50 g upwards. Explore the full selection of gold bullion bars at GoldInvest24.
The 100 g format closes the minted series at the top — it is the highest denomination produced by Argor-Heraeus using die stamping. Above 100 g (250 g, 500 g, 1 kg), the manufacturer offers cast variants exclusively. The percentage premium at 100 g reaches the series minimum — the difference relative to 50 g is modest, yet each step up the denomination ladder further lowers per-gram acquisition costs.

What to look for when buying a 100 g bar
Packaging completeness — the bar should be in its original, unopened manufacturer blister with assay card. The serial number stamped on the bar must match the number on the assay card. Given the highest unit value in the minted series, confirming authorised distribution chain origin is especially important. The 100 g format is the last denomination produced by the minting method — buyers who value the mirror finish and dimensional precision of die stamping should be aware that higher denominations are available exclusively as cast bars.

Frequently asked questions — 100 g Minted Gold Bar Argor-Heraeus
Is the 100 g Argor-Heraeus gold bar VAT-exempt?
Yes. The bar meets the definition of gold bullion (minimum 995/1000 fineness, market-accepted weight) and is exempt from VAT under Council Directive 2006/112/EC (Art. 346). The buyer pays only the net product price.
What is an assay card and what is its purpose?
An assay card is a manufacturer's certificate confirming the bar's weight, fineness, and authenticity. The serial number on the card matches the number stamped on the bar. The Argor-Heraeus assay card is crucial for resale — its absence may require additional verification, reducing secondary-market liquidity.
What is the difference between a minted 100 g and a cast 100 g bar?
Both variants contain identical 100 g of 999.9/1000 gold with LBMA accreditation. The difference lies in manufacture and finish: the minted bar is die-stamped from a gold strip, featuring a smooth, mirror-like surface. The cast bar is formed by pouring molten gold into a mould, resulting in a rougher, industrial texture. At 100 g, the cast variant is often more prevalent on the market, but the minted bar offers superior surface aesthetics and dimensional precision.
What is the difference between the minted and Kinebar series?
The minted series comprises standard bars with a smooth, mirror-like surface, serial number, and assay card. The Kinebar series differs by featuring an additional KineGram hologram on the reverse — a dynamic security element that changes its pattern with the viewing angle. Both share identical 999.9/1000 fineness and LBMA accreditation.
Why is 100 g the most cost-efficient denomination in the minted series?
The percentage premium over the spot price decreases with weight — fixed production, certification, and packaging costs are spread across more metal. At 100 g, this effect peaks within the minted series: the cost per gram of gold is closest to the spot price across all Argor-Heraeus minted formats. For buyers prioritising premium minimisation, the 100 g minted bar is the optimal choice — higher denominations (250 g, 500 g, 1 kg) are available exclusively as cast bars.
How should 100 g Argor-Heraeus bars be stored?
Bars should be kept in the original manufacturer blister. Given the considerable metal value of a 100 g bar, a safe rated at least class 0 (EN 1143-1) or a bank deposit box is essential. Home insurance should include a precious metals clause with adequate coverage. With multiple 100 g bars, a professional vault offering allocated storage with full insurance is recommended.
How many troy ounces does a 100 g bar contain?
A 100 g bar contains 3.21507 troy ounces (1 oz t = 31.1035 g). That is over three troy ounces — the standard trading unit for precious metals on global exchanges (LBMA, COMEX, SGE).
