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).

Heriberto Jara (1866-1939) was a union member, military man, politician, and revolutionary from Veracruz. He was one of the first to graduate from the Antón Lizardo Naval Academy. He directed, in 1914, the action of the cadets of this school against the North American invasion. He joined the Constitutionalist Army and attained the rank of General. He was a congressional representative for his native state to the Constitutional Congress of Querétaro. In Congress, he joined the radical group and greatly influenced the edition of Article 123, as well as others that gave profound social meaning to the Constitution. A well-known figure in both Veracruz and national politics, he occupied several government positions when the Revolution was over until he retired to private life. Heriberto Jara was a distinguished man who dedicated his life to attaining revolutionary ideals.
