| Additional information |
In 1990, Banco de México was deep into planning what would become the 1993 redenomination — a lopping of three zeros that converted 1,000 old pesos into one new peso. Pattern strikes in unconventional metals like lead were part of the internal testing and approval process, evaluating die performance and planchet behavior before committing to production specifications. Most never left the mint through official channels.
The Calles series itself honored Plutarco Elías Calles, president from 1924 to 1928 and the founder of what eventually became the PRI. That this denomination reached the pattern stage in lead suggests serious consideration before the redenomination rendered the entire face value obsolete before a single circulation strike was made.
