2025 Mexico 1 kilo Silver Aztec Calendar PL-70 PCGS (Green Label)

---

Struck by the oldest minting institution in the Americas, La Casa de Moneda de Mexico, this massive coin showcases a level of detail that is rarely achieved. The Mexican Mint, which began its operations in 1535, has crafted this piece from a full kilogram (32.15 troy ounces) of 0.999 pure silver. With a highly restricted mintage of only 60 pieces, this release represents an exceptional achievement in modern minting, certified in flawless Proof 70 condition. The reverse of the coin is dominated by the complex Aztec calendar system. This ancient timekeeping method merged a solar cycle of 365 days with a sacred ritual cycle of 260 days. Every microscopic detail of the original stone calendar is rendered here in high relief, accompanied by the Mexican Mint's historic 'Mo' mint mark, the $100 face value, the 2025 year of issue, and the inscription '1 kg Plata Pura Ley 0.999'. On the obverse, the coin displays a central sculptural depiction of the Mexican national shield, surrounded by the words 'Estados Unidos Mexicanos'. Encircling this central design is a series of historical coats of arms used by the nation throughout its past. Backed by the authority of Banco de México, this monumental silver piece stands as a stunning fusion of ancient cultural heritage and modern numismatic artistry.
