    3D-Printable Greek Stater Coin of Alexander the Great

    Alexander the Great died in 323 BCE in Babylon in 323 BC. Coins had been in circulation for a little less than three hundred years by then, with the innovation beginning in Lydia, then Persia, and flowing to the empires around the Mediterranean from there. This coin was struck within a year of Alexander the Great’s death and follows in the tradition begun by his father in Macedonia. The coins and then the idea (and ideas) behind them, just as Hellenism did, would then flow to Greek colonies around the coasts to far away lands in most modern European, Northern Africa, and Indian countries from there.
