City letter carrier cap badge, number 5164
City Free Delivery Service · 1887
This wreath-style badge, made to department specifications, was worn by a Philadelphia, Pennsylvania, letter carrier. The badge is made of German silver, a metallic element containing copper, zinc, and nickel. The Post Office Department chose this metal because of its hardness and resistance to corrosion, an important consideration since the letter carrier's work constantly exposed the badge to harsh and fluctuating weather conditions.
