Around the 18 th century, America was discovered and soon became the dominant producer of silver. In Middle ages, Central Europe became the heart of silver mining and production. This trend continued until met a severe downfall with the fall of the Roman Empire. Later, Romans became the biggest dealers of silvers and their economy circulated about ten times more silver than the combined amount of silver present in Europe in 800 AD. The rise of Athens was attributed to the nearby mines, which supplied about 30 tons of silver in 300 years (from 600 to 300 BC). Greeks and Romans also used silver as currency.
