On August 20th, last Friday, the spot gold price exceeded $2,500/ounce, a new record high, and the gold bar usually weighs about 400 ounces, which means that the price of each gold bar has reached a milestone of more than 1 million US dollars. Of course, there are subtle differences in the data. According to the London Bullion Market Association, in the global precious metals trading center London, gold bars usually weigh about 400 troy ounces, but the pure gold content can also be between 350 and 430 ounces. In addition, there are also smaller, lower-total gold bars for individual purchase, such as those sold by Costco.
