The Mexican 50 Peso gold coin (also known as a “Centenario”) commemorates Mexico’s liberation from Spain. On the obverse side, an Angel of Independence holds a laurel wreath signifying victory and a broken chain representing freedom. The coin is 20 percent larger than its American Gold Eagle counterpart. First minted in 1921, the Mexican 50 Peso equals the gold purity of popular pre-1933 United States gold coins including the Saint-Gaudens coin. With its lower premium, however, investors can purchase a piece of history for a better price than its American counterpart.
