1 Peso Jaguar - 1/4 oz Silver Bullion

The Jaguar bullion series launched in 1991 as Mexico's answer to the American Silver Eagle and Canadian Maple Leaf, offering fractional silver options that the Libertad series did not cover at the time. Casa de Moneda de México positioned these as accessible entry-point bullion, though the series was discontinued after a relatively short run, making mid-series dates like 1998 quietly harder to source in quantity than either the first or last years.

KM#661 specifically refers to the 1/4 oz denomination within the series — the fractional Jaguar coins share a family of KM numbers across their weight increments.
