Silver is often overshadowed by gold, but in the modern industrial world, it is arguably the more vital metal. Because it is the most electrically conductive, thermally conductive, and reflective metal on the periodic table, it is often called the "Indispensable Metal."
Silver's discovery dates back to around 5,000 BC in Anatolia (modern Turkey), where it was first mined and used for ornaments. By 3,000 BC, Mesopotamians and Egyptians employed it for currency and jewelry, valuing its luster and malleability. The Greeks (600 BC) introduced silver coins, while the Romans expanded mining in Europe, using it for trade and warfare.
In India, silver's history traces to the Indus Valley Civilization (2,500 BC), where artifacts show its use in beads and vessels. The Mauryan Empire (300 BC) minted silver punch-marked coins ("pana"). During Mughal rule, silver rupees standardized economy. Colonial Britain flooded India with silver, leading to the 1893 rupee devaluation crisis.
