In 9 AD when Wang Mang usurped the Han throne and changed the dynastic title to Hsin, he declared all gold the property of the state. When he died, his treasuries held 700,000 catties of gold, or about 180,000 kilograms. This was the amount of gold in the Chinese state treasury in the 1st Century AD, and it was roughly equal to all the gold held by the Roman Empire at that time.
王莽篡漢，國號改為新，施行「黃金國有」政策，到他死的時候，府庫藏金有七十萬斤，大約相當十八萬公斤左右，這是中國在西元一世紀時國庫的儲金量，與當時羅馬帝國的黃金儲量相去不遠。
