Minted bars are made from gold blanks that have been hand cut to the required dimensions from a flat piece of gold. Markings are almost always applied by presses. <a href="http://en.wikipedia.org/wiki/ChipGold" title="ChipGold">ChipGold</a> is a relatively new form of gold bar consisting of a small ingot (1-20 grams) in a sealed and certified package the size of a <a href="http://en.wikipedia.org/wiki/Credit_card" title="Credit card">credit card</a>.<br /><br /><h2><span class="mw-headline">Weights and values</span></h2> <p>One <a href="http://en.wikipedia.org/wiki/Troy_weight" title="Troy weight">troy ounce</a> = 31.1034768 grams.
