The statement that the largest number of coins issued by the Guptas were of copper is not correct.
The Gupta period is renowned for its extensive and high-quality gold coinage (Dinara). While the Guptas also issued silver and copper coins, gold coins were the most numerous and artistically significant during their rule, especially during the reigns of prominent rulers like Chandragupta II and Kumaragupta I.
Gupta kings issued a variety of gold coins depicting various royal activities and Hindu deities. Silver coins were introduced later, primarily after the conquest of the Western Kshatrapas. Copper coins were also issued but in smaller denominations and were generally less common than gold coins, particularly in the core regions of the empire.
