20 Pesos Plan Marina

The "Plan Marina" 20 Peso commemorative marks the Mexican Navy's role in disaster relief operations, particularly the coordination effort following major seismic events and hurricane responses along both Mexican coastlines. Mexico's bimetallic 20 Peso platform has been used since the late 1990s as the country's primary vehicle for circulating commemoratives, producing dozens of institutional and cultural issues — which means collector fatigue for the series is real, and premiums above face value remain modest for most types including this one.
