Bosnia and Herzegovina's convertible mark system, introduced in 1998 under the Dayton Agreement's financial architecture, required a new coinage tied to the currency board arrangement that pegged the mark to the Deutschmark at parity. The Central Bank was legally prohibited from issuing credit or financing government deficits — an unusual constraint written specifically to prevent the monetary manipulation that had fueled wartime hyperinflation in the former Yugoslav republics.

The long production span across this single type reflects how little demand there was to redesign a coinage that was never controversial.
