Based on a research by Callieri, most of the symbols of the Frataraka's coins like the flag, the memorial building and the appearing posture of the person standing opposite to it are derived from the Achaemenids. Daryaee believes that though the Fratarakas probably did not know the proper application of a building like Ka'ba-ye Zartosht, it still had an ideological importance to them. Therefore, it can be deduced from the similarity of Ardashir's coins with the late coins of local Persian governors there was a movement based on Persian traditions and the local Persian governors' adornment of it. However that does not necessarily mean that Ardashir was related to the local Persian shahs in all affairs.
