1 Ounce Silver Aztec Round

This 1 ounce round is struck in .999 fine silver.

The obverse features the Aztec sun stone, also called the calendar stone, which consists of a 365-day calendar cycle called xiuhpōhualli (year count) and a 260-day ritual cycle called tōnalpōhualli (day count). These two cycles together form a 52-year "century", sometimes called the "calendar round". The xiuhpōhualli is considered to be the agricultural calendar, since it is based on the sun, and the tōnalpōhualli is considered to be the sacred calendar.

On the reverse is Cuauhtémoc, the Aztec ruler of Tenochtitlan from 1520 to 1521, making him the last Aztec Emperor. The name Cuauhtemōc means "one who has descended like an eagle", and is commonly rendered in English as "Descending Eagle", as in the moment when an eagle folds its wings and plummets down to strike its prey. This is a name that implies aggressiveness and determination.
