caption: The image shows a ruler next to a coin with an image of a woman on it, resting on a white surface. The coin appears to be a tetradrachm, a type of ancient Roman coin, with a diameter of approximately 1.5 mm. The woman on the coin is wearing a long, flowing dress and has her hands clasped in front of her. Her hair is pulled back in a bun and she has a serene expression on her face.
