Depicts the seal of the United Mexican States.

The Seal of the United Mexican States is a modified version of the national coat of arms, with the addition of the full official name of the country Estados Unidos Mexicanos, in a semi-circular accommodation in the upper part of the seal. Current and past Mexican peso coinage have had the seal engraved on the obverse of all denominations.

The coat of arms depicts a Mexican golden eagle perched on a prickly pear cactus devouring a rattlesnake. To the people of Tenochtitlan this would have strong religious connotations, but to the Europeans, it would come to symbolize the triumph of good over evil (with the snake sometimes representative of the serpent in the Garden of Eden).

Pedro Moreno Gonzalez (1775–1817) was an insurgent in the Mexican War of Independence. From the start of the War of Independence, Pedro Moreno was friendly with the principal insurgent caudillos, earning him repeated threats of imprisonment, until he formed his own insurgent army with campesinos from the Bajío region. He established his center of operations in the fort of Sombrero, from which he attacked the royalist forces of Bajío and Los Altos. He survived the worst years of the royalist repression and in 1817, joined his forces with those of Francisco Javier Mina. Together they undertook various successful military endeavors in the Bajío, until in October of that year Moreno died in combat in the vicinity of the Hacienda de Venadito. Pedro Moreno was undoubtedly an outstanding fighter for independence, even under the most adverse conditions.
