1 German Mark Okrug Mostar

Okrug Mostar was one of several administrative districts of the Republic of Bosnia and Herzegovina that issued emergency local currency during the 1992–1995 war, as the national supply of Yugoslav dinars collapsed and the new Bosnian dinar struggled to reach isolated communities. These district-level issues filled an immediate transactional gap and were denominated in German marks — not because the Okrug had any formal currency authority, but because the Deutsche Mark had become the de facto unit of account across much of the former Yugoslavia long before the war began.

The pink paper is characteristic of wartime improvisation; normal banknote stock was unavailable.
