Below I have my example of a Mexican Commemorative. It is actually one of the series of Endangered Species in Mexico Collection. That is inscribed on the reverse in Spanish, "ANIMALES EN PELIGRO DE EXTINCION / EN MEXICO". Mine is a 2000 River Crocodile, "CROCODRILO DEL RIO". It shows a great picture of a crocodile centered on the coin. His or hers mouth is opened against a grass background. Above that is the date 2000 and the mint mark of Mexico City below it. To the left of the crocodile is the denomination, $5. To the left of everything is the Latin name of the species, (Crocodylus acutus). It is a very busy reverse but it all fits nicely on the well designed reverse.
