Silver Alexander the Great tetradrachm coin struck during the lifetime of Alexander the Great, the first world conqueror and one of the most remarkable men in history, his armies capturing most of the civilized world. He not only introduced a uniform currency system, but promoted trade and commerce. Desiring to be supreme ruler, all provinces were required to worship him as a God. Alexander believed he was a direct descendant of Hercules. Before each battle and after each victory, ritual sacrifices were performed honoring both Hercules and Zeus and he selected their images to appear on these coins.
