50 Roubles Second Provisional Siberian Administration

The Provisional Government of Siberia at Omsk — the anti-Bolshevik administration nominally led by Admiral Kolchak after his November 1918 coup — issued an enormous volume of paper currency throughout 1919 as its military position progressively deteriorated. Printing was entirely local, which imposed real constraints on security quality; the guilloche work is competent but far below the standard of notes the same government had produced earlier with foreign assistance.

By late 1919, Kolchak's forces were in full retreat eastward. The Red Army took Omsk in November of that year, and most of this currency became worthless almost immediately after issue.
