One troy ounce represents a fundamental unit within the physical gold market. JM Bullion explains that 1 troy ounce is the standard weight for a gold coin or bar, corresponding to the unit used when the global gold spot price is quoted. Its current catalogue includes a dedicated selection of 1 oz gold bars from different manufacturers and mints, including products from PAMP Suisse, Valcambi, Rand Refinery, Perth Mint, Asahi and other producers. This gives the 1 oz category substantial variety while maintaining the same one-troy-ounce gold weight across individual products.

JM Bullion also offers 1 oz gold coins alongside its bar selection, making the weight available across different physical bullion formats. The company’s 1 oz gold-bar catalogue includes both new products and secondary-market or varied-condition offerings, with specifications depending on the individual product. For the JM Bullion UK proposition, the 1 oz category can therefore serve customers looking specifically for one-troy-ounce physical gold, whether their preference is a gold bar or a recognised bullion coin.
