This exceptional gold double daric was minted during the reign of Mazaeus, the Persian satrap of Babylon from 331 to 328 BC. It is one of only three specimens certified by NGC, making it an unparalleled rarity in the realm of ancient coinage. The coin features a design that mirrors Mazaeus' renowned silver staters from Tarsus in Cilicia, but with the added prestige of gold and the absence of any legend.
Experts believe this coin may have been overstruck on a worn double daric, possibly one bearing the Hero King obverse. The reverse showcases the iconic lion and bull motif, a nod to the ancient Lydian Empire and a testament to the rich numismatic heritage of the region.

Historical Context
After the defeat of King Darius III by Alexander the Great, Mazaeus was appointed as the governor of Babylon. Faced with the choice to continue his governance under Alexander's rule or face replacement, Mazaeus chose the former, aligning himself with the new Macedonian authority. This coin likely represents an early emission during this transitional period, reflecting Mazaeus' shift in allegiance and the evolving political landscape of the time.
