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).

Portrait of Venustiano Carranza to the right, 7 points above (braille 100).

Venustiano Carranza Garza (1859–1920) was one of the main leaders of the Mexican Revolution, whose victorious northern revolutionary Constitutionalist Army defeated the counter-revolutionary regime of Victoriano Huerta (February 1913-July 1914) and then defeated fellow revolutionaries after Huerta's ouster. He secured power in Mexico, serving as head of state from 1915-1917. With the promulgation of a new revolutionary Mexican Constitution of 1917, he was elected president, serving from 1917 to 1920. Known as the "Primer Jefe" or "First Chief" of the Constitutionalists, Carranza was a shrewd politician rather than a military man.

In the 1920 election, in which he could not succeed himself, he attempted to impose a virtually unknown, civilian politician, Ignacio Bonillas, as president of Mexico. Northern generals, who held real power, rose up against Carranza under the Plan of Agua Prieta, and Carranza was assassinated fleeing Mexico City.
