5 Roubles Woolly rhinoceros

Transnistria — the narrow strip of land between the Dniester River and the Ukrainian border, unrecognized by any UN member state — issues collector coinage through its Republican Bank as a form of de facto sovereign expression. The woolly rhinoceros (Coelodonta antiquitatis) was a genuine presence across the Eurasian steppe during the Pleistocene, and fossils have been recovered from the region's river sediments.

KM#279 belongs to a broader prehistoric fauna series that Transnistria has used to attract the international bullion collector market — one of the few revenue streams available to an economy operating outside global financial institutions. Mintage figures are unverified by independent sources.
