Page "Heliokles II" Paragraph 7

The existence of numerous overstrikes helps locate the reign of Heliokles II in relation to other Indo-Greek kings.

Heliokles overstruck coins of Agathokleia, Strato I, and Hermaeus.

Conversely, Amyntas overstruck coins of Heliokles II.

These overstrikes would suggest that Heliokles II reigned around 95 – 85 BCE, and was a contemporary of Amyntas and Hermaios
