| Additional information |
The "SUD" designation on this pattern refers to an experimental alloy trial conducted by the Casa de Moneda in 1986 as Mexico weighed composition options for its post-reform coinage following the peso's catastrophic devaluation earlier that decade. Multiple planchet materials were tested under coded designations before final specifications were locked. Most of these trial pieces were never publicly released, surviving only in institutional holdings or through direct acquisition from mint personnel.
