Brief History of the Gold Standard in the United States

fas.org

gold 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

The gold resources in the United States, however, are only a small portion of global gold resources. Substitutes: Base metals clad with gold alloys are widely used in electrical and electronic products, and in jewelry to economize on gold; many of these products are continually redesigned to maintain high-utility standards with lower gold content.
