History & Notable Facts
The 2010 Calderón Bicentennial coin features a reverse design that subtly incorporates the iconic "Grito de Dolores" bell, linking it directly to Mexico's independence declaration.
That detail often surprises newcomers, who expect something more flamboyant from a bicentennial piece. Struck at the Casa de Moneda in Mexico City, it used .999 fine silver, a standard for modern commemoratives, with a diameter of 40 millimeters to accommodate the intricate engraving.
Mintage figures are murky; official records from that era aren't always reliable, possibly due to administrative oversights. As for myths, I've heard tales of hidden messages in the eagle's feathers, but that's just collector folklore—nothing verifiable.
Some might think it's rare, but it's not.
