1 Peso Disco de la Muerte - 1/4 oz Silver Bullion

The "Disco de la Muerte" nickname — Death Disc — was given to this issue by Mexican dealers and collectors, not out of morbidity but practicality: the coin's small diameter and relatively high silver purity made it notoriously easy to confuse with common circulation pieces, leading to more than a few being spent at face value. Banco de México issued these fractional Libertad pieces in 1997 and 1998 as part of an expansion of the onza plata series into smaller denominations intended to broaden retail bullion access.

The two-year run was short. Low public uptake killed the denomination before it found its footing.
