The early coins of the Gupta period are undoubtedly influenced by the Kushanas. But as the Gupta Empire progressed the coins began to be more and more indigenous. The coins of Chandra gupta II can be called as purely Indian.
Following things may be noted with regard to the indianite of Gupta coins.
Skanda Gupta for the first time issued golden coins of 114 grains. The king and queen represented in these coins are purely in Indian dress.
Like the goddesses of the Kushanas, the early coins of the Gupta period represent Lakshami seated on the throne. But later on Lakshami has been representing either seated on the lotus or on the lion.
The later coins of the Gupta period do not have the Indianity of the Gupta coins.
The later coins of the Gupta period there is a king in a circular form, which is different than Kushanas.
The later silver coins of the Gupta period are free from the sake influence.
From the early period Gupta coins used the Sanskrit language and the Brahmi script. This thing indicates that the course of time Gupta coinage had freed itself from foreign influence and had become purely Indian.
