2020 Mexico 1 kilo Silver Aztec Calendar (w/Box & COA)

Struck in a massive format containing 32.15 troy ounces of pure silver, this 100 Pesos coin from 2020 is a testament to the minting art of the Casa de Moneda de México. The piece carries a very limited mintage of just 250 units globally, making it a rare encounter for those who appreciate large-format precious metals. Backed by the Banco de México, this coin brings a monumental archaeological treasure into a modern numismatic format, continuing a design tradition that first debuted in a one-kilo silver edition in 2007. The reverse side of the coin is dominated by a highly detailed rendering of the Aztec calendar stone, an ancient monument representing a complex timekeeping system. This system integrated a solar cycle of 365 days alongside a ceremonial cycle of 260 days, which together aligned every 52 years to mark an Aztec century. At the heart of the stone is the visage of Tonatiuh, the sun deity, surrounded by panels that depict the eras of previous worlds. Surrounding this intricate central design are the inscriptions indicating its weight and purity, including "1 kg Plata Pura Ley 0.999", along with the denomination of "$100", the year "2020", and the historic "Mo" mint mark. On the obverse, the coin celebrates Mexico's national identity. The central image features the modern Mexican National Shield, which is encircled by the words "Estados Unidos Mexicanos". Framing this central emblem is a circular gallery of various historical coats of arms used by the nation throughout its past, offering a visual journey through the country's evolving heritage.
