Introduction

In 1943 the Mexico City Mint would replace its circulating silver 20 centavos coin with a larger bronze issue with a new design featuring the Pyramid of the Sun.

The Pyramid of the Sun is one of Mexico’s most famous landmarks located in the ancient pre-Columbian holy city of Teotihuacan and is also the 3rd largest pyramid in the world. The design was unique to Mexico and proved extremely popular as it remained in production until 1974.

Design

The obverse design features the Mexican coat of arms, an eagle clutching a snake while it perches on a prickly pear cactus. On the outer periphery is the phrase “ESTADOS UNIDOS MEXICANOS” or as translated to English “United Mexican States”.

The reverse design features the Pyramid of the Sun in front of the mountain Cerro Gordo. Above the pyramid is a Phrygian Cap with Rays, the legend “LIBERTAD” is engraved into the cap and the cap divides the denomination “20”. Immediately above the pyramid is the mint mark “Mo” for the Mexico City Mint.

At the base of the pyramid is name of the ancient holy city of Teotihuacan, Beneath the design ios the word “CENTAVOS” and year of issue.
