Dinar - Hormizd I Crown of boya

Hormizd I ruled for less than a year — his reign ran from roughly 270 to 271 AD by most reckonings, though some numismatic literature stretches the attribution window to accommodate posthumous or transitional issues. The "Crown of Boya" designation refers to a specific headdress variant used to distinguish die groups within the Indo-Sasanian sequence, a classification system developed by Robert Göbl whose Kushan reference numbering remains the working standard despite ongoing disputes over attribution between the Kushano-Sasanian and Indo-Sasanian series.

Göbl 735/9 sits in a tightly clustered group of gold issues whose dies show relatively rapid deterioration.
