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).

At the center, the image of the reverse of a Peso de Caballito (Miniature Horse Peso) the United Mexican States, 1 Peso 1914; at the upper side, parallel to the coin frame, the legend NUMISMATIC HERITAGE OF MEXICO; on the left side, the Mexican mint mark, while on the right field is the $100.

This beautiful coin, the first commemorative coin of its kind in Mexico, was minted to celebrate the 100th Anniversary of the Cry of Dolores which started the War of Independence from Spain. It was designed by the French artist Charles Pillet. It is known as a Miniature Horse Peso because of the horseback rider of Freedom holding a laurel branch in his right hand and a torch in his left; in the background there is a bright sun and in the exergue the mint year.

The Cry of Dolores was uttered from the small town of Dolores, near Guanajuato in Mexico, on September 16, 1810. It is the event that is considered the beginning of the Mexican War of Independence. The "grito" was the pronunciamiento of the Mexican War of Independence by Miguel Hidalgo y Costilla, a Roman Catholic priest. Since October 1825, the anniversary of the event is celebrated as Mexican Independence Day.
