The earliest evidence of silver in India is found in the Harappan culture. The Harappan civilization, also known as the Indus Valley Civilization, existed from approximately 3300 BCE to 1300 BCE in the northwestern regions of the Indian subcontinent. Excavations at various Harappan sites have revealed silver artifacts and ornaments, indicating that silver was known and used by the people of that time.

It`s worth noting that silver was also used in later periods of Indian history. The Chalcolithic cultures of Western India, which existed around 2500 BCE to 1500 BCE, also had evidence of silver usage. Additionally, silver punch-marked coins were used in ancient India from around the 6th century BCE onwards. These coins were stamped with various symbols and served as an early form of currency.

While the Vedic texts, which are ancient Indian scriptures dating back to the 2nd millennium BCE, mention various metals and their importance, specific references to silver in the Vedic texts may not be as prevalent as in the archaeological evidence from the Harappan culture, Chalcolithic cultures, or punch-marked coins.
