Brief History of the Gold Standard in the United States
fas.orggold left the country and silver was the de facto standard. In 1834, the gold content of the dollar was reduced to make the ratio 16 to 1. As a result, silver left the country and gold became the de facto standard. In addition, gold discoveries drove down the value of gold even more, so that even small silver coins disappeared from circulation. In
