50 Roubles Karjalan Tasavalta

Part of Russia's long-running "Regions of the Russian Federation" series, this issue commemorates the Republic of Karelia, a federal subject bordering Finland whose territorial status has been politically freighted since the Winter War of 1939–40, when Finland ceded significant portions of historical Karelia to the Soviet Union. The Finnish name on this coin — Karjalan Tasavalta — reflects that contested heritage.

Silver-plated copper-nickel was adopted for these regional 50-rouble pieces largely as a cost measure following the 2014 sanctions and ruble collapse, which made silver bullion issues economically untenable for mass commemorative production.
