Coins from Mesopotamia
Mesopotamia is a historical region in West Asia situated within the Tigris–Euphrates river system.

The Sumerians and Akkadians (including Assyrians and Babylonians) dominated Mesopotamia from the beginning of written history (c. 3100 BC) to the fall of Babylon in 539 BC, when it was conquered by the Achaemenid Empire. It fell to Alexander the Great in 332 BC, and after his death, it became part of the Greek Seleucid Empire.

It was lost fairly quickly to the Parthian Empire, but a number of important silver coins were struck in e.g. Seleucia on Tigris and other Greek cities.
