1 Zloty Polski - Aleksandr I

The Złoty Polski series issued under Alexander I emerged from a peculiar political fiction: the Kingdom of Poland established by the Congress of Vienna in 1815 was nominally independent, with Alexander wearing its crown separately from his Russian imperial title. This constitutional arrangement demanded its own coinage, distinct from Russian issues, a concession to Polish national sentiment that Alexander tolerated until the November Uprising of 1830 ended the experiment entirely.

The .593 fineness was a deliberate step down from earlier Polish silver standards, quietly aligning Warsaw's output with Russian monetary policy from the outset.
