[QUOTE="user 4386, post: 583610, member: 4386"] I don't think there is such a thing as a metric ounce - an ounce is not a metric unit - so I don't think it has much to do with us going metric. Your choices are avoirdupois or troy (i.e. a retained troy unit because of currency consideration - to prevent confusion in buying and selling gold, as it caused us - versus the later "British" system of ounces and pounds). Not metric. Major mints (The Royal Mint, Perth Mint, Royal Canadian Mint, Johnson Matthey, PAMP Suisse, Credit Suisse, Swiss Bank, Metalor, Heraeus, Valcambi, UBS, Baird Mint and Umicor) cast troy ounce bars, so I wonder where yours come from? Mines quote production in troy ounces when they use ounces. I assume they are stamped with their purity as well, not just a document? 400 ounce bars always demand a lower premium. I have never seen avoirdupois gold bars before (the only other type I know is the 32.15 troy ounce kilobar of 1000 grams). Where are they cast? I am wary of source because China produces lots of fake bars with tungsten cores (almost identical in mass to gold). However that has nothing to do with the units of measurement, which have been declared in this case. One buyer bought 80 tonnes of fake bars....[img]https://www.prospectingaustralia.com/forum/img/member-images/4386/1605757144_gold_tungsten.jpg[/img] [/QUOTE]
