caption: The image shows a silver coin with the head of a man on it, set against a white background. The coin is likely from the Roman Empire, as it is a tetradrachm, a type of currency used in the reign of Emperor Alexander the Great. The man on the coin is wearing a crown and a long robe, and is holding a sword in one hand and a shield in the other. He has a stern expression on his face, and his hair is combed back.
