A Mexican centenario is a gold coin first minted in 1921 commemorating the 100th anniversary of Mexico’s freedom from Spain. The Centenario contains 1.20565 Troy ounces of gold in an alloy of 90 percent gold and 10 percent copper. At 37 millimeters in diameter, the coin is 21.6 karats gold.
Popular with collectors and investors, the centenarios minted from 1921 to 1931 are more highly valued, especially the first and last year of the series. Production restarted in 1943 and continued through 1947 and periodically in subsequent years. The face value of 50 pesos is for legal purposes only. The coin features the image of Winged Victory with a laurel wreath in her right hand and broken chains in her left as well two Mexican volcanoes, Popocatepetl and Iztaccíhuatl, in the background.
