History |
Egyptians used silver without complex refining processes before 3500 BC. The Spaniards during the 16th century AD found one of the most important silver mines. The largest active mines now include those at Hildago, Mexico. By at least the 8th century BC most likely all countries of the ancient Middle East were using both silver and gold as currency. A prohibition was placed on silver coinage in the US in 1873 as a result of the gold discoveries in the mid-19th century. In the 1960's the Treasury Department ceased issuing silver certificates, the paper money secured by silver. |
