The current coat of arms of Mexico has been an important symbol of Mexican politics and culture for centuries. The coat of arms depicts a Mexican golden eagle perched on a prickly pear cactus devouring a snake. 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).
The Seal of the United Mexican States is the seal used by the government of Mexico in any official documents issued by the federal, state or municipal authorities. It 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.
