Posted another coin to Thingiverse at https://www.thingiverse.com/thing:5900668.
This one is of a coin from the Mauryan empire. Chandragupta Maurya established the Mauryan Empire in the Magadha region of India shortly after the death of Alexander the Great in the 320s BCE. By then, coins from Persia and the Greek city states had been traded with peoples in the Indian subcontinent for centuries. India hadn’t been united by previous empires in the way Chandragupta did so, and the empire he established lasted until 185 BCE.
