Vasishka's reign remains one of the more poorly documented stretches of Kushan rule — his precise relationship to Kanishka III is disputed, and his coinage is the primary evidence historians use to establish his existence at all. The gold dinars attributed to him are relatively scarce compared to earlier Kushan issues, suggesting either a shortened reign or a contraction of the empire's western minting capacity under pressure from the resurgent Sasanian Empire, which had begun aggressively encroaching on Kushan territory by the mid-third century.
Göbl's sequencing places this type within a narrowing dynastic window before the Kushano-Sasanian kings effectively absorbed the western minting tradition entirely.
