La Vaquita marina
The "Vaquita Marina" (Phocoena Sinus) was unknown to the scientific
world until 1958 when three skulls were found on the shores of the California
Gulf. This is the smallest of all adult cetasea, it's not a common species
and is endemic of the Gulf of California. Due to the rarity of this species
and also to the commercial fishing activities, it is considered as a species
in extinguishing danger.
This coin commemorates the XX anniversary of United Nations Environmental
Program.

Aniversario la Revolución mexicana |
Revolución mexicana
The commemorative coins of heroic deeds or being outstanding on some kind
of sport, allow us to transmit to future generations the recollection
of events which have profoundly marked our social life. They also allow
us to have memories and feel proud of our past as well as to renew our
ardent desires to build a more prosperous Mexico. By virtue of the foregoing,
in 1985, silver coins to commemorate the 75 anniversary of the 1910 Mexican
Revolution were struck. Such coins have the effigies of heroes of the
Revolution such as Emiliano Zapata, Francisco I. Madero, Venustiano Carranza
and Francisco Villa, having the Mexican Revolution Monument in the background.

Fondo Mundial para la naturaleza |
Mariposa Monarca
The WWF World Wide fund for Nature, came into being in 1961. It was established
by a small group of people concerned about environmental issues. This
organization struggles to preserve the natural and ecological processes
by keeping safe from injury, the different species and the diversity of
the eco-system. They want to be sure resources are available now and in
the future. This group is involved in promoting actions to abate contamination
and to considerably lower the exploitation of natural resources.
The WWF through the "Spink Modern Collections" coordinated this program
in which several countries participated. México struck a silver coin with
the image of the "Monarch Butterfly".
One of the most astonishing marvels of nature, is the migratory phenomenon
of the Monarch butterfly. Approximately one million of this type of butterflies
make a journey of approximately 5,000 kilometers to hibernate in the same
woods which their ancestors did the year before, to continue reproduction
of their species. This species is currently in extinguishing danger.
