1 Dollar 5 Mark banknote

Liberia's dual-denomination issues of the early 2000s were produced primarily for the collector market, denominated simultaneously in Liberian dollars and German marks in a transparent bid to attract European buyers before euro conversion rendered the mark obsolete. The timing was deliberate — the German mark ceased to be legal tender in January 2002, making any mark-denominated piece an immediate curiosity rather than a functioning instrument of exchange.
