Archaic Greek coinage seems to have had a very wide circulation in the Achaemenid Empire. Many of them were discovered in coin hoards throughout the Achaemenid Empire such as the Ghazzat hoard and the Apadana hoard, and also very far to the East, such as the Kabul hoard or the Pushkalavati hoard in Ancient India, following the Achaemenid conquest of the Indus Valley. Generally, Greek coins (both Archaic and early Classical) are comparatively very numerous in the Achaemenid coin hoards discovered in the East of the Achaemenid Empire, much more numerous than Sigloi, suggesting that the circulation of Greek coinage was central in the monetary system of those part of the Empire.
