25 Roubles Baron Munchausen

Transdniester — the narrow strip of land between the Dniester River and the Moldovan-Ukrainian border — has operated as an unrecognized breakaway state since 1992, and its central bank has long used novelty coinage as a soft-power curiosity, partly to generate collector revenue in the absence of broader international trade. Baron Munchausen's connection to the region is genuine: Karl Friedrich Hieronymus von Münchhausen served in the Russian Imperial Army during campaigns against the Ottomans in the 1730s and 1740s, and Bendery — now Bender, one of Transdniester's main cities — was among the fortresses where he was stationed.
