10 g Minted Gold Bar Argor-Heraeus — 999.9/1000 fineness, LBMA Good Delivery, assay card with serial number
10 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 10 g format opens the standard-weight segment in the Argor-Heraeus minted series — this is the threshold above which the percentage premium over the spot price drops to levels markedly more favourable than the 1-5 g micro-denominations. The dimensions of 27 × 15 × 0.7 mm give the bar classic, USB-stick-like proportions that facilitate both storage and visual identification. Weighing just over one-third of a troy ounce (0.32150 oz t), the 10 g format is prized for its optimal balance of market liquidity, unit cost, and portfolio flexibility.

Why the 10 g Minted Gold Bar from Argor-Heraeus
The 10 g format is the turning point in the minted series — the percentage premium drops below micro-denomination levels while the bar retains a compact form factor for easy storage and secondary-market trading. 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 10 g bar combines substantial metal value with high liquidity — large enough to minimise the premium's impact on total cost, yet small enough for flexible partial liquidation without selling a significant position.
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, specialising in gold and silver refining for the Swiss banking sector. In 1999, it merged with the precious metals division of Heraeus Holding GmbH — a German industrial group with a tradition dating back to 1851, giving rise to the present-day Argor-Heraeus 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, confirming its exceptionally rapid attainment of the highest industry standards. 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 exact 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. Unlike the Kinebar series, minted bars do not feature a KineGram hologram — their authenticity relies on the serial number, assay card, and manufacturer's hallmark.
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 10 g format opens the standard-weight segment where the percentage premium sits markedly below that of the 1-5 g micro-denominations. Fixed production and certification costs spread over twice the metal content of the 5 g format, yielding a better premium-to-weight ratio. Buyers focused on the best per-gram cost may also consider 20 g, while 10 g remains the classic choice combining moderate outlay with an optimal premium.

What to look for when buying a 10 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. Unlike micro-denominations (1-5 g), the 10 g format already offers a markedly lower percentage premium — it is the first denomination where fixed production costs lose their dominant impact on the final price. Comparing the premium with the 20 g format is worthwhile to assess whether doubling the outlay yields a proportional benefit.

Frequently asked questions — 10 g Minted Gold Bar Argor-Heraeus
Is the 10 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.
Why is 10 g the optimal format for many buyers?
The 10 g format opens the standard-weight segment where the percentage premium falls below the levels typical of 1-5 g micro-denominations. Weighing just over one-third of a troy ounce (0.32150 oz t), the bar is easy to compare against global spot quotes. The financial outlay remains moderate enough for regular purchases, while a single bar already represents substantial metal value suitable for standalone resale.
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.
How does the premium on 10 g compare with smaller formats?
The 10 g format offers a significantly lower percentage premium than the 1-5 g micro-denominations. It is the first denomination where the premium approaches the levels seen on larger bars (20-50 g), making it one of the most cost-efficient choices in the minted segment.
How should 10 g Argor-Heraeus bars be stored?
Bars should be kept in the original manufacturer blister. Optimal conditions: dry, dark location at room temperature. For a few pieces, a home safe (minimum class S1 per EN 14450) suffices. For higher total metal value, at least class S2 (EN 14450) or class 0 (EN 1143-1) is recommended. Home insurance should include a precious metals clause with a sum adequate for the stored holdings.
How many troy ounces does a 10 g bar contain?
A 10 g bar contains 0.32150 troy ounces (1 oz t = 31.1035 g). That is just over one-third of a troy ounce — the standard trading unit for precious metals on global exchanges (LBMA, COMEX, SGE).
