50 Groszy Oflag II-D

Oflag II-D was a German camp for Polish officer prisoners of war located at Gross Born (now Borne Sulinowo) in Pomerania. Like several other officer camps, it operated an internal scrip system — prisoners were credited with ersatz wages under the Geneva Convention's provisions for officer POWs, and this note was the medium through which those credits circulated within the wire. The handstamp is the only security feature because sophisticated printing was simply unavailable; the scrip was meaningful only within a closed population where every user knew every other user.

Campbell 3792 is one of the scarcer Oflag issues. The camp was evacuated westward in early 1945 as Soviet forces advanced, and most scrip was abandoned or destroyed during the forced march.
