50 g Green Gold Bar by Valcambi — minted from certified recycled gold, .9999 fine, LBMA Good Delivery
50 g of .9999 fine gold (999.9/1000) from the Green Gold series by Valcambi SA — a Swiss refinery holding LBMA Good Delivery accreditation since 1968. All precious metal used in production is sourced 100% from recycling and verified in accordance with LBMA Responsible Gold Guidance and OECD Due Diligence. Each bar carries an individual serial number and is delivered in a blister with an assay card confirming weight, fineness and authenticity.
Green Gold is Valcambi's flagship responsible-sourcing programme. The buyer receives a product identical in fineness, weight and LBMA accreditation to the standard minted series, but with the additional guarantee of no new mining, a reduced carbon footprint and full supply-chain traceability. The 50 g format is a large denomination in the minted-bar segment — the premium per gram reaches one of the lowest levels in the entire Green Gold series, while the one-off outlay remains considerably lower than at 100 g. Chosen by buyers building a large precious-metals position with an optimal premium-to-weight ratio.

Why this product?
- Certified recycled gold — all metal in the Green Gold series is sourced 100% from secondary sources (recovery of jewellery, electronics and industrial materials). Every batch is verified for supply-chain compliance under LBMA Responsible Gold Guidance and OECD Due Diligence Guidance — a guarantee of no links to armed conflict and no exploitation of new deposits.
- Large denomination with a near-minimum premium — the 50 g format is one of the most cost-effective denominations in the Green Gold series in terms of premium per gram. Production, recycling-certification and packaging costs are spread across fifty times the metal of a 1 g bar — the premium approaches the level of the 100 g format, at a considerably lower one-off outlay. An efficient format for buyers building a large precious-metals position.
- Identical fineness and accreditation to the standard series — Green Gold delivers the same 999.9/1000 standard and the same LBMA Good Delivery accreditation as the classic minted series by Valcambi. The difference concerns the raw-material source only — not the technical parameters of the product.
- Mirror finish and individual serial number — each bar is minted from rolled strip, producing a smooth, mirror-finish surface with clear markings. The serial number on the bar and assay card ensures full traceability on the secondary market.
- LBMA Good Delivery since 1968 — Valcambi SA meets the highest quality standards of the London Bullion Market Association. Bars are accepted without additional verification at bullion banks, dealers and precious-metals exchanges worldwide.
Valcambi SA — Swiss precious-metals refinery
Valcambi SA has operated since 1961 in Balerna, Canton Ticino, southern Switzerland. The refinery processes the four major precious metals — gold, silver, platinum and palladium — with an annual throughput exceeding 2,000 tonnes. It is one of the world's largest and most recognised precious-metals processors, serving central banks, state mints and global bullion dealers.
Valcambi received its LBMA Good Delivery accreditation for gold in 1968 — confirmation that the refinery's products meet the stringent standards of the London Bullion Market Association for fineness, weight and production consistency. The refinery holds LBMA accreditations for all four major precious metals — making it one of the few worldwide with a complete accreditation set.
The Balerna facility covers the entire production cycle — from raw-material refining (both mine-doré and recycled metal) through rolling, blanking and minting to final packaging. Valcambi produces both minted bars with a smooth surface and cast bars with a rough texture — both forms at the same 999.9/1000 fineness. The Green Gold series comprises exclusively minted bars.
Valcambi operates responsible-sourcing programmes aligned with OECD Due Diligence and LBMA Responsible Gold Guidance standards. The refinery undergoes regular audits by independent certification bodies, ensuring full supply-chain traceability from raw material to finished product.
Green Gold — certified recycled gold
The Green Gold programme is Valcambi's flagship initiative for sustainable gold sourcing. All precious metal in bars from this series is sourced 100% from recycling — from the recovery of bullion jewellery, electronic components, industrial materials and other secondary sources. No Green Gold batch contains gold from newly exploited deposits (mine-doré).
The supply chain of every batch is audited against two key international standards: LBMA Responsible Gold Guidance — which sets requirements for refineries regarding metal-source traceability and prevention of conflict financing — and OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas — the framework standard for due diligence in mineral supply chains from conflict zones.
Gold recycling has a significantly lower carbon footprint than primary mining. According to the World Gold Council, processing secondary gold generates up to 99% fewer CO₂ emissions per gram than open-pit mining. For precious-metals buyers, institutions and entities subject to ESG reporting, the Green Gold series offers a way to accumulate physical gold while minimising the environmental impact of the purchase.
Technically, Green Gold bars are identical to the classic minted series by Valcambi — same 999.9/1000 fineness, same LBMA Good Delivery accreditation, same minting process from rolled strip, same dimensions and packaging (blister with assay card). The only difference is the certified, fully traceable raw-material source — exclusively secondary gold.
Formats and denominations — Valcambi Green Gold series
Valcambi SA offers Green Gold bars in eight denominations: 1 g, 2.5 g, 5 g, 10 g, 20 g, 50 g, 1 oz (31.1035 g) and 100 g. All items are minted bars with a mirror finish, packaged in a blister with an assay card bearing the Green Gold certificate. The series comprises exclusively minted bars — there are no cast equivalents in the Green Gold programme.
The 50 g format is one of the large denominations in the Green Gold series — fifty times the metal of a 1 g bar and more than triple the troy-ounce format (31.1 g). The premium per gram is among the lowest in the series, approaching the level of the 100 g format. Chosen by buyers who want to build a large position in sustainable gold with an optimal premium-to-weight ratio, without the one-off outlay required by the 100 g format. Also popular as a weight-diversification element alongside troy-ounce and 100 g bars.

What to look out for when buying?
Before buying, check the current gold price and compare the bar price with the spot price. The premium over spot for the 50 g format is among the lowest in the Green Gold series — production, recycling-certification and packaging costs are spread across a large amount of metal. The only format with an even lower premium per gram in this series is the 100 g bar, at twice the one-off outlay.
The smooth, mirror-finish surface is a natural feature of the minting process. Key factors for resale are: individual serial number, assay card in an intact blister and manufacturer recognition (Valcambi, LBMA Good Delivery). The Green Gold certificate is an additional identifying element but does not affect the buyback price — dealers value the bar based on weight, fineness and manufacturer accreditation, regardless of whether the metal is sourced from recycling.
The 50 g Green Gold format is the choice for buyers seeking a large denomination in sustainable gold — with a premium near the series minimum and full LBMA accreditation.

FAQ — frequently asked questions
What is the Valcambi Green Gold series?
Green Gold is a programme by Valcambi SA in which bars are produced exclusively from gold sourced 100% from recycling — from the recovery of jewellery, electronics and industrial materials. The supply chain is audited under LBMA Responsible Gold Guidance and OECD Due Diligence Guidance. In terms of fineness (999.9/1000), accreditation (LBMA Good Delivery) and form (minted), Green Gold bars are identical to the standard minted series by Valcambi.
Are the fineness and weight of a Green Gold bar the same as the standard series?
Yes. Green Gold bars have the identical 999.9/1000 (.9999) fineness, identical weight and identical LBMA Good Delivery accreditation as the classic minted series by Valcambi. The difference concerns the raw-material source only — in Green Gold it is 100% recycled gold; in the standard series it is a mix of primary and secondary gold.
Does the Green Gold bar come with an assay certificate?
Yes. Every Green Gold bar is packaged in an original blister with an assay card containing the serial number, fineness, weight, assayer's signature and Green Gold certification mark. Breaking the blister reduces the market value — storage in the original packaging is recommended.
Is recycled gold of lower quality than mined gold?
No. Gold is a chemical element (Au, atomic number 79) — once refined to 999.9/1000, it is chemically identical regardless of source. Recycled gold undergoes the same refining process as mined gold and achieves the same purity. The Valcambi assay certificate confirms the fineness of each bar individually.
Are Green Gold bars VAT-exempt?
Yes. Valcambi Green Gold bars meet the definition of bullion gold (minimum 995/1000 fineness, bar form accepted on the precious-metals market) and are VAT-exempt under EU Directive 98/80/EC. The exemption applies to all denominations in the series.
What liquidity do Green Gold bars have on the secondary market?
Valcambi Green Gold bars have the same liquidity as the standard minted series — dealers value them based on weight, fineness and manufacturer accreditation (Valcambi, LBMA Good Delivery). The Green Gold certificate is an additional identifying element but does not affect the buyback mechanism in the precious-metals trade.
How should I store a 50 g Green Gold bar?
Ideally in the original blister, in a dry place away from moisture. Given the value of a 50 g gold bar, a home safe rated at least Class 0 (EN 1143-1) or Class I, or a bank safe-deposit box with insurance, is recommended. The blister protects the surface and preserves the full market value of the bar.
