About 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.
