| Additional information |
These years bracket Mexico's worst debt crisis in modern history. The government's 1982 default on foreign debt triggered capital flight, peso devaluations, and inflation that reached nearly 160% annually by 1987 — conditions under which a 20-peso coin became practically worthless faster than the mint could strike it. Production volumes across this range were enormous, driven not by demand for coinage but by the arithmetic of inflation making small denominations obsolete almost immediately after release.
By 1990, monetary reform was already being planned; the nuevo peso redenomination of 1993 would erase three zeros from the currency, retiring this issue entirely.
