Assertion: Hoards of Roman coins have been found from archaeological sites in south India.
Reasoning: South India was a part of Roman Empire in ancient times.

The Assertion is correct but the Reason is incorrect.

The Kushanas were responsible for issuing the earliest and largest quantities of gold coins. These coins closely matched the weight of gold coins issued by contemporary Roman emperors and Parthian rulers of Iran. Remarkably, these Kushan gold coins have been unearthed from various locations in north India and Central Asia. The extensive use of gold coins during this period highlights the significance of the commercial activities that were occurring.

Interestingly, archaeological discoveries in south India have also revealed hoards of Roman coins. This evidence suggests that trade networks were not restricted by political borders. Despite South India not being part of the Roman Empire, there were substantial trade connections that facilitated the exchange of goods and currency between these distant regions. These historical findings shed light on the vibrant trade interactions that characterized this era and the global nature of commerce even in ancient times.
