50 Roubles Belarus - Ukraine. Spiritual heritage. Irmologion

The Irmologion is a liturgical chant book of the Eastern Orthodox tradition, and the Belarusian-Ukrainian manuscript tradition produced some of its most distinctive regional variants between the 16th and 18th centuries — a period when both territories sat under the Polish-Lithuanian Commonwealth and later fell under competing religious pressures from Rome and Constantinople alike. The 2020 "Spiritual Heritage" series from the National Bank of Belarus used these shared cultural artifacts as a vehicle for asserting a broader Slavic ecclesiastical identity.

KM#689 is among the heavier issues in the series, struck in oxidized fine silver with selective gilding — a finishing technique the Minsk Mint applied with considerable consistency across this thematic program.
