In 1910, a new peso coin was issued, the famous Caballito, considered one of the most beautiful of Mexican coins. The obverse had the Mexican official coat of arms (an eagle with a snake in its beak, standing on a cactus plant) and the legends "Estados Unidos Mexicanos" and "Un Peso." The reverse showed a woman riding a horse, her hand lifted high in exhortation holding a torch, and the date. These were minted in .903 silver from 1910 to 1914.
