Kilo Gold Bars

Kilo gold bars are large-format bullion bars containing one kilogram of gold — equivalent to approximately 32.15 troy ounces — and represent one of the most substantial single-bar denominations available to bullion buyers. They are produced by a range of internationally recognized refiners and mints, including PAMP Suisse, Valcambi, Perth Mint, Heraeus, and others, each striking or cast their bars to a fineness of .9999 (24-karat). Most kilo bars carry the refiner's hallmark, bar serial number, assay certification, and fineness stamp either engraved directly on the bar or on an accompanying assay card.

Within the broader gold bar market, kilo bars occupy a distinctive position between mid-size 10 oz bars and the institutional 400 troy oz London Good Delivery bar. Their weight and format make them a preferred denomination for buyers seeking a meaningful concentration of gold in a single piece. Both minted (pressed with smooth faces and sharp edges) and cast (poured, with a rougher crystalline surface texture) formats exist across refiners, giving collectors and buyers a choice between presentation styles.

At Lone Star Coins, the kilo gold bar inventory spans multiple refiners and both minted and cast formats, with pricing updated against the live spot market.
