25 Cents Sinop Air Station

Sinop Air Station was a highly classified NSA signals intelligence facility on Turkey's Black Pont peninsula — one of the most sensitive listening posts along the Soviet Black Sea coast throughout the Cold War. The NCO Open Mess scrip issued here served a practical purpose: keeping dollars off the local economy, as required by Status of Forces agreements, while accommodating a base population that was small, isolated, and operating under strict security protocols.

The APO New York address is standard for European theater military installations, masking geographic location in official mail routing. Scrip of this type was typically redeemed or destroyed at the end of each MPC conversion cycle, which is why base-specific mess scrip survives in far smaller quantities than general Military Payment Certificates.
