| Additional information |
In 1989, the Casa de Moneda de México was actively developing bimetallic technology ahead of the new peso revaluation program that would ultimately redenominate the currency in 1993. Pattern pieces from this period were struck in limited numbers for internal evaluation and were rarely released through official channels, making survivors genuinely scarce rather than artificially so. Mexico was among the earliest mints in the Western Hemisphere to pursue bimetallic circulation coinage at scale, with these trial strikes forming part of that technical groundwork.
The Pn190 designation places this among a documented sequence of patterns from the late Banco de México modernization push.
