⅙ Dinar - Ardashir I type III2/2

Ardashir I founded the Sasanian dynasty by defeating the last Arsacid king, Artabanus IV, at the Battle of Hormozdgan in 224 AD — the same year this coinage type begins. The fractional dinar denominations were struck in notably small quantities relative to the full dinar, and surviving examples in any condition are genuinely scarce. Göbl's classification of this as type III2/2 places it within the later phase of Ardashir's coinage, after successive die revisions refined the royal image toward the more standardized portrait conventions his successors would inherit.
