50 Kopecks Without signature, Second Provisional Siberian Administration

The Provisional Government of Siberia issued this note during the chaotic overlap between Kolchak's White administration and the collapsing anti-Bolshevik front. The absence of a signature is not an error or omission — unsigned small-denomination notes of this type were deliberately released without authorization signatures as a practical measure, given the speed at which currency needed to reach circulation across an enormous and increasingly unstable territory.

Over twelve million printed, yet surviving examples in any respectable condition are genuinely uncommon — the Siberian civil war economy consumed paper money at a brutal rate, and much of the circulated stock was destroyed or abandoned during the Red Army's advance westward through 1919–1920.
