Few images in world history pack more detail into a circle than the Aztec Sun Stone, and the Aztec Calendar 1 oz silver bar translates that monument into stacking silver. Each bar contains 1 troy oz of .999 fine silver struck with one of the most intricate designs in the bullion market, giving buyers museum-grade artwork at round-level premiums.
Key Features:
- Purity and Weight: .999 fine silver, 1 troy oz
- Metal Type: Silver
- Obverse Design: The Aztec Sun Stone calendar in full engraved detail with Mesoamerican border motifs
- Reverse Design: Portrait of Cuauhtémoc, the last Aztec emperor, with weight and purity
The obverse reproduces the Aztec Sun Stone, the 24-ton basalt monument carved around 1500 and unearthed beneath Mexico City’s central plaza in 1790. At its center is the face of the sun deity, surrounded by concentric rings representing the 20 day-signs of the Aztec calendar, cosmological eras, and rays pointing to the cardinal directions. The engraving carries the pattern to every band, and stepped temple motifs and serpentine figures fill the corners of the frame. It’s a design that rewards a magnifying glass, and it made this series one of the best-selling themed bars in silver.
The reverse honors Cuauhtémoc, the final emperor of the Aztec Empire, who led the defense of Tenochtitlan against the Spanish in 1521. He appears in left-facing profile wearing an eagle-feather war headdress and ornamented ear discs, his name inscribed beneath the portrait. The inscriptions ONE TROY OUNCE and .999 FINE SILVER flank the portrait above and below, all inside a stepped geometric border echoing Mesoamerican stonework.
The bar format stacks flat and tight, and the design’s popularity keeps secondary demand steady, an advantage generic bars can’t claim. It also makes a striking gift for anyone with an interest in Mexican heritage or ancient history.
Serious artwork, a real historical subject, and a full ounce of silver at a modest premium make this bar an easy addition. Order the Aztec Calendar 1 oz silver bar today.
