At first the coat of arms of Volhynia on coins is in the form of a white cross on a red shield, as in 14th-century Lutsk under Prince Dmitry Gediminovych. Two centuries later, the coat of arms appears on silver półkopek and gold ducat coins of Sigismundus II Augustus, King of Poland. The date on the obverse is 1564, over the value of XXX (30 grosz). The shield with the cross of Volhynia is depicted on the reverse.
The gold ducats were minted with a Latin inscription “Sigismundus Augustus, King of Poland, Grand Duke of Lithuania”. On the reverse was a shield with the cross of Volhynia, and a Latin inscription: “gold coin of the Grand Duchy of Lithuania”.
The king’s portrait is in three variants: with a short beard (1547–1548), with a long beard (1549–1561), with a long and forked beard (1563–1571).
