1 Dinar - Kanishka I

Kanishka I expanded the Kushan Empire to its greatest territorial extent, controlling the Silk Road corridor between Rome and Han China and extracting enormous wealth from the transit trade — wealth that funded precisely this kind of heavy, consistent gold coinage. The Kushan dinar was deliberately calibrated close to the Roman aureus in weight to facilitate that commerce, and Kushan gold circulated as recognized tender well beyond imperial borders.

Göbl 26 is among the more frequently encountered die types in the Kanishka series, though "frequent" is relative for third-century Central Asian gold.
