10 000 Roubles With Security Thread

Pick 30b is a transitional issue within the second Belarusian ruble series — a family of notes that had been in continuous circulation since 1992 and was chronically devalued by inflation so severe that by the time this print run was authorized, 10,000 rubles bought almost nothing. The addition of a security thread to an existing design, rather than issuing a replacement series, reflects the practical difficulty Belarus faced in overhauling currency infrastructure while managing an exchange rate in freefall.

The Republic ultimately replaced the entire series in 2016 at a redenomination rate of 10,000 old rubles to 1 new ruble — exactly this note's face value collapsed into a single coin.
