History & Notable Facts
The Aztec Calendar 20 Pesos coin immortalizes the ancient Aztec sun stone on its obverse, a motif drawn from a massive basalt monolith unearthed in Mexico City, weighing a staggering 24 tons.
That design choice reflected Mexico's post-revolutionary push to reclaim indigenous roots, with the coin struck in 90% gold and featuring a liberty cap on the reverse.
Mintage varied by year, but exact figures for some issues remain murky due to incomplete records from the era.
While myths persist about these coins funding Aztec revivals, they simply circulated as currency.
Not every gold piece tells a story; some just glint quietly in a dealer's tray.
