50 Soʻm

Uzbekistan's first banknote series, issued in 1992 following independence from the Soviet Union, was a transitional currency in the literal sense — the so'm did not yet exist as a permanent unit, and these notes circulated alongside Soviet ruble remnants while the new monetary system was being assembled. The 1992 series was printed before the definitive som coinage and higher-denomination notes could be organized, making it a stopgap in the truest meaning.

The watermark security on this series is notably rudimentary by international standards of the period, reflecting the practical constraints of commissioning currency on short notice from available printing facilities.
