1 ounce Gold Gold Bars for Sale

1 ounce gold bar

The troy ounce is the standardised measurement for gold bullion. This measurement only accounts for the actual pure gold content, so a one ounce gold bar actually weighs a little more than an regular ounce. This is because all gold contains at least traces of other materials. Because apothecaries used a system of weights that were similar, a troy ounce is sometimes called an apothecary ounce. They mean the same thing. The international gold price is based on the troy ounce with a fineness indication of .995.
A troy ounce is the equivalent of 31.103 grams. Many mints produce gold bullion with a higher purity level, so while the price of gold is determined based on the 99.5% purity level, gold bars often feature a higher level of fineness. This makes them worth a little more than their less pure counterparts, but only by a small amount.

Because one ounce bars are the standard of measure for gold bullion, these are very popular with both investors and collectors. As with all officially sanctioned gold bars, these come in standardised dimensions, as well as in standardised weights. Each bar is 31 mm in length, 18 mm in width, and 1 mm in depth. Each one also bears an inscription indicating the fineness of the gold, its weight, and information relating to the refinery where it was produced. Gold bullion bars also come with a certificate of authenticity. Although the bars are marked as weighing one ounce, this is referring to troy ounces. The actual weight is a little more than a normal ounce.
