Gold Bars
Gold bars are refined gold products manufactured by accredited private mints and refineries, struck or cast to standardized weights and purity levels. This category includes bars ranging from fractional gram sizes — such as 1 gram and 2.5 gram — up to the widely traded 1 troy oz format, with .9999 fine gold (24-karat) being the dominant fineness across modern production. Most bars are sealed in tamper-evident assay cards or blister packaging that includes an assay certificate confirming weight and fineness. The gold bar market is anchored by a handful of internationally recognized refineries, each with its own distinctive design language. PAMP Suisse, based in Switzerland, is known for its Lady Fortuna obverse design — a figure of the Roman goddess of fortune — which has become one of the most recognized motifs in the bullion world. Valcambi Suisse, another Swiss refinery, produces cleanly designed bars with serialized assay packaging and also offers CombiBar formats at select weights. Both refineries carry LBMA (London Bullion Market Association) accreditation, a benchmark for refinery standards in the global gold market. On CoinDuffle, buyers will find gold bars from multiple dealers spanning a range of weights, refineries, and packaging formats. Current listings include fractional gram bars ideal for those building a varied weight portfolio, as well as the full 1 oz bar — the most liquid and widely recognized size in the bullion market. Listings are sourced from established dealers and include both "Our Choice" generic assay bars and branded refinery pieces. Additional weights and refinery options may appear as dealer inventory expands.

Frequently asked questions
Gold bars are produced across a broad weight spectrum. This category currently features fractional sizes — 1 gram and 2.5 gram — as well as the standard 1 troy oz bar. Beyond these, the broader market also includes 5 gram, 10 gram, 1 kilogram, and larger cast bars. Fractional bars appeal to collectors building diversified holdings, while the 1 oz bar is the most commonly traded size among bullion buyers.
.9999 fine gold indicates a purity of 99.99%, meaning the bar contains no more than 0.01% of other metals. This is the standard fineness for most modern investment-grade gold bars from accredited refineries such as PAMP Suisse and Valcambi Suisse. It is sometimes referred to as 'four nines fine' and represents the highest commonly available purity in the retail gold bar market.
An assay card is tamper-evident packaging — typically a sealed plastic blister or card — that encases a gold bar along with a certificate confirming its weight, fineness, and refinery of origin. Many premium bars from PAMP Suisse and Valcambi Suisse are sold 'in assay,' meaning the original sealed packaging remains intact. The assay card also typically carries a unique serial number for individual bar identification.
Both are Swiss LBMA-accredited refineries with strong international reputations. PAMP Suisse is particularly recognized for its Lady Fortuna design series, featuring artistic relief designs on the obverse. Valcambi Suisse bars tend to feature a more understated, minimalist design and are also known for their CombiBar products. Both produce .9999 fine gold bars across a range of weights and ship in serialized assay packaging.
'Our Choice' gold bar listings indicate that the dealer will fulfill the order with a .9999 fine gold bar from an accredited refinery of their selection — the buyer receives a bar meeting the stated weight and fineness specifications, but the specific brand or refinery is not guaranteed. These listings are common for standard 1 oz bars and are typically fulfilled with well-known refineries based on current dealer inventory.
