2025 Mexico 1 kilo Silver Aztec Calendar PF-70 NGC (Coat of Arms)

---

Struck by the historic Casa de Moneda de Mexico, which dates back to 1535, this massive silver piece represents a pinnacle of modern minting. Weighing a full kilogram, the coin is crafted from 0.999 fine silver and carries a face value of 100 Dollars. It has been certified in perfect Proof 70 Ultra Cameo condition, highlighting the incredible depth and contrast of its complex engraving. The reverse side displays the legendary Aztec calendar stone, a monumental design rooted in a sophisticated timekeeping system. This ancient calendar tracked time through two overlapping wheels, combining a 365 day solar year with a 260 day ritual cycle. At the very center of the stone is the detailed face of Tonatiuh, the Aztec deity of the sun. Surrounding this central image are the inscriptions CALENDARIO AZTECA, the Mo mint mark of the Mexico City Mint, the year 2025, and the metal specifications reading 1 kg PLATA PURA LEY 0.999. On the obverse, the coin features the modern national shield of Mexico, which is encircled by a series of historical coats of arms used throughout the nation's past. The central emblem is accompanied by the inscription ESTADOS UNIDOS MEXICANOS. Guaranteed by the Banco de México, this extraordinary issue is highly exclusive, with a maximum mintage of just 60 pieces.
