The image is of a famous Mexican Poet nun... good mix right? The coin is worth 1 new peso in the conversion (know on the dual tones coins with a NP ) the New Pesos became just Peso again around the year 2000. This one cannot be used in Mexico - but in the day it was worth around 10 US cents at the time they changed to NP to raise the values. There are a few from this era in Mexico that are wonderful silver - a great value that is sure to grow in value.
