10 Zlotys Jan III Sobieski

Jan III Sobieski is best remembered for commanding the relief force at the Battle of Vienna in September 1683, where a combined Christian army broke the Ottoman siege — the last serious Ottoman push into central Europe. Poland's role in that battle was decisive, yet within a generation the Polish-Lithuanian Commonwealth had entered the long decline that would end in partition. This coin was issued well after that historical reckoning, during a period when NBP was actively building a collector series around figures central to Polish national identity.
