History of Gold Pesos

First minted in 1905, the Mexican Gold Peso coins commemorate the centennial of Mexico's hard won independence from Spanish colonial rule. The Mexican War for Independence lasted from 1810 to 1821. A Mexican-born Spaniard, Miguel Hidalgo y Costilla led other colonial-born Spaniards, along with Mestizos and Amerindians, in an uprising against the Spanish conquistadors. Although Hildago shortly following his initial revolt, the Mexicans were ultimately successful in ousting their oppressors, and on September 27, 1821, the Treaty of Cordoba was ratified, giving Mexico sovereignty from Spain.

In 1910, the Columna de la Independencia (the Statue of Independence) was erected in Mexico City's Paseo de Reforma, commemorating the start of the war. Atop a massive column is a figure of Winged Victory. This angel is made of bronze and plated in 24-karat gold. She holds a laurel crown, the symbol for victory, in her right hand. In the left, she clutches a broken chain that represents Freedom. At the base of the statue, a mausoleum hosts the remains of war heroes.

The Angel quickly developed as a symbol of national pride in Mexico, and its image was chosen to adorn the Mexican Gold Peso. In 1921, the Mexican 50 gold peso was first minted. Each 50 Peso gold coin's reverse depicts Winged Victory in the foreground, with Mexico's volcanoes, Popocatepetl and Iztaccihauti, in the background. On the obverse, the original Mexican coat of arms was etched in crisp detail. The coat of arms features an eagle atop a cactus, devouring a serpent.

The national coat of arms is depicted on the obverse of other denominations of gold peso coins.

The reverse of the 20 Pesos Gold Coin has the words "Veinte Pesos" (Twenty Pesos) surrounding the Aztec Calendar Sun Stone.

The reverse of the 10 Pesos Gold Coin, the 5 Pesos Gold Coin and the 2.5 Pesos Gold Coin all contain a portrait of revolutionary leader Miguel Hidalgo y Costilla. The reverse of these smaller denomination gold pesos also includes the denomination's face value surrounding the Hidalgo portrait.

The smallest of the gold pesos, the 2 Peso Gold Coin shows a Mexican celebratory wreath, along with the denomination and year of minting.
