JM Bullion’s gold-bar catalogue covers a broad range of physical gold bars by weight and production format. Its current selection includes gram gold bars, 1 oz gold bars, 5 oz gold bars, 10 oz gold bars and kilo gold bars, with products available from recognised refiners and mints. JM Bullion explains that gold bars can vary in weight, purity and style, while its catalogue provides buyers with multiple options within these categories. For the UK market, this gives JM Bullion UK a clearly defined gold-bar offering built around physical bullion in different sizes, allowing buyers to identify products according to the quantity of gold they wish to acquire.

JM Bullion also distinguishes between cast gold bars and minted gold ingots. Its guidance explains that cast bars are produced by pouring molten gold into a mould, while minted ingots begin as long cast bars and undergo additional processing through a stamping press to achieve their specified size, shape and engraved finish. JM Bullion notes that the additional production process associated with minted ingots generally results in different premiums, with cast gold bars generally carrying lower premiums than minted ingots. The company identifies 1 oz and 10 oz among the most commonly purchased gold-bar weights and also highlights the popularity of 1 kilogram bars, giving UK buyers several established weight categories to consider within the JM Bullion gold-bar range.
