Why did the Safavid use both silver and copper?

The Safavid Empire used both silver and copper primarily to facilitate trade and support their economy. Silver was valued for its higher worth and was often used for larger transactions and trade with foreign nations, while copper was more accessible and utilized for everyday commerce and smaller transactions. This dual currency system allowed for greater flexibility in economic activities and helped stabilize the monetary system within the empire. Additionally, the use of both metals helped in managing inflation and ensuring a steady supply of currency.
