1 Silver Rouble

Bank Polski operated under the tight supervision of the Russian imperial administration following the failed November Uprising of 1830–31, which stripped the Kingdom of Poland of most of its autonomous institutions. By the 1850s, the bank was effectively a subordinate instrument of St. Petersburg's financial apparatus, not an independent central bank. The 1851 silver rouble notes were denominated in the Russian monetary unit precisely because the złoty-based system had been suppressed following the 1841 monetary unification decree, which forcibly aligned Polish circulation with the imperial rouble standard.

Bank Polski was liquidated in 1885, absorbed into the Russian State Bank's Warsaw branch. Notes from this series rarely survived in collectible condition — institutional destruction accounted for most.
