This is a striking and historically significant Policía Bancaria e Industrial México D.F. badge from the mid-20th century, crafted for Mexico's specialized banking and industrial police force in the Federal District. Measuring 5.5cm x 8cm and weighing a substantial 48.9g, this heavy brass badge features intricate enamel work and symbolic detailing:
 
A large five-point star topped with the iconic Mexican eagle, set against a vibrant red enamel background.
 
A central banner in the national colors (green, white, and red) with "Policia" in blue enamel.
 
The phrases "Bancaria e Industrial" and "Mexico; D.F." with painted blue backgrounds, along with the identification number "464" on a blue enamel field.
 
Originally produced with a straight pin back, this badge was professionally converted to a screw post fastener for secure wear, reflecting its practical use over time. The design embodies the authority and national pride of Mexico’s specialized police units, tasked with protecting financial and industrial institutions in the capital.
 
Ideal for collectors of law enforcement memorabilia, Mexican history, or vintage insignia, this badge represents a unique niche in policing heritage. The condition shows age-appropriate wear, including minor enamel fading and brass tarnishing, but the bold colors and structural integrity remain intact.
