Bosnia and Herzegovina introduced its convertible mark currency in 1998 under the terms of the Dayton Agreement, with the exchange rate hard-pegged to the Deutsche Mark — and later, automatically to the euro at the fixed DEM/EUR conversion rate. The currency was designed in part to function as a unifying instrument across the two entities of the postwar state, administered through a currency board that legally cannot conduct discretionary monetary policy.

The currency board structure means no coins of this series were ever minted to manage economic cycles — only to meet transactional demand, which keeps mintage decisions unusually straightforward for a modern issue.
