The Argor-Heraeus 1 oz minted gold bar contains one troy ounce of 999.9 fine gold, approximately 31.1035 g. Unlike metric weights such as 20 g or 50 g, the one-ounce format connects directly with a traditional unit used across international precious-metals markets.
Why choose a 1 oz gold bar?
One troy ounce equals approximately 31.1035 g. It is not the same as the ordinary avoirdupois ounce used for everyday goods, which weighs about 28.35 g.
That distinction matters because gold and other precious metals are traditionally quoted internationally in troy ounces.
Compared with a 20 g bar, one ounce contains roughly 11.1 g more gold. Compared with 30 g assembled as one 20 g and one 10 g bar, the ounce contains slightly more metal but keeps the position in one unit.
The trade-off is divisibility. One 1 oz bar is one product, while a 20 g plus 10 g combination creates two independent units.
