Mexico 1985 100 pesos KM-505

from the Mountain Groan Collection

By the late 1970's, the Mexican economy was running into trouble. Political mismanagement, corruption, an antiquated tax structure were feeding inflation. Coin types, once stable in the early part of the century, began turning over more rapidly as inflation ate away their purchasing power. While this gave employment to coin designers and engravers, it limited their scope of action as progressively cheaper alloys were adopted. The peso, originally a large silver coin (KM 453), progressively shrank until it contained no silver at all. In an attempt to keep silver circulating, progressively larger denominations were introduced and promptly hoarded. In 1985, when authorities wished to promote the upcoming World Cup, the circulating commemorative was a copper-nickel 200 pesos (KM 525). Proof fifty, 100, 200, 250, 500, 1000 and 2000 pesos were minted in gold and silver and sold.
