Heliocles II used a reverse of standing Zeus, who was a common deity among the later Indo-Greek kings.

Senior has instead suggested a connection with Demetrius III, who used a similar reverse of standing Zeus.

Heliocles II issued Indian silver with portrait (diademed, helmeted or spear-throwing) / standing Zeus and bronzes with bearded diademed portrait (Heliocles or Zeus) / elephant.

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

These overstrikes suggest that Heliocles II reigned around 95–85 BC and was a contemporary of Amyntas and Hermaeus [2]
