The twentieth coin of the series shows John III Sobieski of the Janina coat of arms, the Grand Hetman of the Crown, elected king after the victory of Chocim in May 1674 and crowned on 2 February 1676. He gained fame in Europe after the victory at Vienna and is considered one of the greatest commanders and rulers in the history of Poland. He had reform plans regarding foreign and domestic policy and he wanted to secure the succession of his eldest son James (Jakub) to the Polish throne. The reverse of the coin features a bust of the king (according to a painting by Marcello Bacciarelli), transferred from a medal, facing right, with Sarmatian-style shaved hair and abundant moustache, in a laurel wreath; in armour with a lion epaulette and a fur-lined cloak, with the cross and star of the French Order of the Holy Spirit. On the obverse of the coin, the text from the reverse of the medal (in translation, slightly shortened) reads: Elected on the 20th day of May Anno Domini 1674, crowned on the 2nd day of February Anno Domini 1676 – as a subject [of King Michał Korybut Wiśniowiecki], he beat the Turks at Chocim, as king he defeated them, freed Vienna from the siege – distinguished for his valour, learning and eloquence – as a subject he took part in internal disturbances, on becoming king he was tormented by the same misfortune.
