The Centenario is a Mexican gold bullion coin first minted in 1921 to commemorate the 100th anniversary of Mexico's independence from Spain. The obverse of the Centenario
contains the image of Winged Victory (El Ángel, El Ángel de la Independencia: "The Angel of Independence"), with a laurel wreath in her right hand and broken chains in her left. Two famous Mexican volcanoes, Popocatepetl and Iztaccíhuatl, rise in the background. The 1821 on the lower left commemorates the year of Mexico's independence.
