Original Item – Only One Available. Original issued badge commemorating the 50th anniversary of the Mongolian State Security’s Special Department, the most classified intelligence dep in socialist Mongolia. Produced in 1972, the design displays a silver sword over a shield with the bold red enamel “50” at its center, marking half a century of secret service operations. The blue border carries the Mongolian inscription for “Special Department,” confirming its direct connection to state security during the Cold War era.

Issued in very limited numbers and reserved only for internal circles of the security apparatus, this badge ranks among the rarest pieces of Mongolian intelligence memorabilia. Surviving examples are scarcely encountered on the market, making it a coveted acquisition for advanced collectors of espionage and Cold War history.
