Hemidrachm - Shapur I

Shapur I's reign encompassed one of the most dramatic military achievements in ancient history — the capture of the Roman Emperor Valerian at the Battle of Edessa in 260 AD, the only time a sitting Roman emperor was taken prisoner in battle. The hemidrachm denomination was a fractional issue produced alongside the larger drachm, likely serving frontier garrison economies and smaller commercial transactions within the expanding empire.

The Göbl classification places this among the earliest Sasanian silver types, with style P representing a relatively controlled die-cutting tradition before later provincial variation crept in.
