100 Pesos Oaxaca - Gold and Silver Proof Issue

This issue belongs to a long-running Mexican series celebrating pre-Hispanic and colonial cultures, with the Oaxaca-themed pieces drawing on the Zapotec and Mixtec heritage of Monte Albán — one of the earliest urban centers in Mesoamerica, occupied continuously for over a millennium before Spanish contact. The Casa de Moneda de México, the oldest mint in the Western Hemisphere, has struck bimetallic proof issues in this format since the mid-1990s, with annual themes rotating across Mexico's distinct regional cultures.

Mintages for individual issues in this series have historically been low, often under 1,000 pieces, though precise figures vary by year.
