20.000 So'm

Uzbekistan's banknote series underwent a significant redenomination in 2017, when the som was rebased at 1:1 — the old currency had simply inflated beyond practical use, with everyday transactions regularly requiring bundles of 1,000-som notes. The 2021 series, of which this is a mid-range denomination, followed revised design and security specifications introduced after that transition stabilized the physical currency infrastructure.

Cotton substrate at this size and weight class is consistent with Uzbek central bank procurement through European security paper suppliers, though the specific mill is not publicly confirmed for this series.
