Mexico was celebrating last year the bicentennial of its independence and the centennial of its revolution. From 2008 to 2010, Banco de Mexico issued thirty-seven 5-peso bimetalic coins celebrating the heroes of those times.
Each coin shows on the obverse the national emblem, the eagle eating the snake, and on the reverse the face and the name of the celebrated hero.
Among those heroes, these ones might remind you some of your history classes: Emiliano Zapata, Pancho Villa (two worldwide famous men from the revolution) and Miguel Hidalgo (priest who was the very first instigator of the independence war against Spain)
Those coins are very popular in the country. In Mexico city in December 2010, it was almost impossible to find some of those coins circulating. Even bank and numismatics shops declared not to have any of them! Reason: people would keep it to be able to offer fulfilled specific collectors as Christmas presents! Who said Mexican are not "coins lovers"?
(by the way: it was way easier to get those coins out of the capital... seems city-dweller and people in the countryside do not see coins the same way...)
