[Winner] Silver [Silver Details] The largest known stockpiles of silver amount to less than 1 billion ounces (such as Comex warehouses and the SLV ETF). If someone (perhaps a government) wanted to buy, say, 100 million ounces of silver, there would be nowhere to buy it at once. It would require buying it on the open market, raising the price of silver in the process. [Gold Details] There are numerous stockpiles of gold; the governments of many countries have plenty of gold on hand. To raise the price of gold, governments would need to add to their stockpiles.
