Issued by Chile in 1983, this $20 commemorative stamp marks the Cincuentenario (50th Anniversary) of Investigaciones de Chile, the country’s national investigative police force founded in 1933. The design features the official PDI emblem placed over a shield and sword, symbolizing discipline, honor, and national security. Printed by the Casa de Moneda de Chile, the stamp displays crisp detail and warm tonal shading that enhances the heraldic insignia. A desirable thematic piece for collectors of law enforcement, national emblems, Latin American history, and Chilean commemoratives.
