This coin is one of my favorite Mexican patterns – it was unfortunately short lived (only 1910-1914) and very few were produced due to the disruptions of the ongoing Mexican Revolution. On the obverse, it shows Liberty riding sidesaddle on a horse, while brandishing the torch of freedom overhead and holding a laurel branch of peace over the horses head. The sun is rising (or setting, if you’re a pessimist) behind liberty and rays of light stretch out behind her and the horse.
On the reverse is a more traditional Mexican pattern – an eagle battling a serpent while standing atop a prickly pear cactus. The legend reads “Estados Unidos Mexicanos”, and under the cactus is the denomination “Un Peso”.
