1 Peso Pattern, Morelos, Uniface

Pattern coinage from the Casa de Moneda de México in this period reflects the mint's internal evaluation process as it worked through a succession of proposed designs ahead of major circulating issues. Uniface strikes — produced on only one die with a blank reverse — were a standard step in that process, allowing engravers and mint officials to assess relief, field quality, and hub integrity before committing to a paired obverse-reverse production run.

The Morelos 1 Peso series of the early 1980s was itself caught between competing pressures: chronic inflation was already eroding the peso's purchasing power so rapidly that the denomination would be largely obsolete within a few years of any new design entering circulation.
