Filibuster Invasion of Baja California Medal (1911)

In 1911, in the midst of the Mexican Revolution, an armed group linked to the Mexican Liberal Party of the Flores Magón brothers occupied towns in Baja California, in a confused episode that the authorities labeled a filibuster invasion due to the presence of foreigners among the rebels.

This silver medal from 1911, of the decorations category, recognized those who took part in defending the national territory against that incursion. The episode raised great concern for the integrity of the country's northern border.

The piece is a testament to a turbulent moment in the early Revolution, when various factions and movements disputed Mexico's course. It documents how the defense of sovereignty on the remote Baja California peninsula earned official recognition.

The "Invasión filibustera a Baja California" medal was struck in 1911. It is made of silver, measures 35.19 mm in diameter and weighs 16.47 grams, struck in Mexico. In the specialized catalog it is referenced as Grove, Medals of México, III #D-352a.

Being a silver medal, its value has a floor: its precious metal content (16.47 grams). Above that, what drives it up is its condition, the small size of the issue, and interest in the subject it commemorates (Invasión filibustera a Baja California). A piece with no wear and its original case is worth considerably more than one that has been handled.
