it is true. In some areas only sell thousands of feet, and some areas selling 999.9 and 999.99 grams of pure gold. Although they are all pure gold, the price and content are still different. Especially in the purchase price, there is a certain difference. Many consumers spend five gold dollars to buy pure gold, only 999. The current five -nine gold is called high -purity gold. Gao Chunjin refers to a gold product with a purity of 99999%, which is marked as AU99999. Pure gold is pure, reddish, and more pure than Wanjin AU9999.
