20 Roubles Polotsk

Polotsk is among the oldest cities in present-day Belarus, with chronicle references dating to 862 AD, and it spent much of the medieval period as the seat of an independent principality that resisted incorporation into Kievan Rus more stubbornly than most. The National Bank of Belarus has issued an extensive series of regional and historical commemoratives in .925 silver since the 1990s, often targeting the collector market rather than circulation — virtually none reached everyday use.

KM#379 belongs to a documented run of 28.28g commemoratives sharing the same planchet specification across dozens of Belarusian issues from this period, a cost-effective approach that kept die preparation as the primary variable expense.
