Wenceslas I (b. 1205 – d. 23 September 1253), also called One-eyed king, was the fourth Czech king from the Přemyslid dynasty, the second son of Přemysl Otakar I and his second wife Constance of Hungary.

Wenceslas was crowned at the time of his father’s reign on 6 February 1228 as a “younger king“ by Siegfried of Eppenstein, the archbishop of Mainz. The reason for the coronation was that Přemysl Otakar I wanted to secure during his life the royal title for his second born son to avoid doubts concerning the legitimity of Wenceslas’ claim to throne. In accord with the Prague and Olomouc bishop and nobles, Přemysl Otakar and Wenceslas stipulated that their successors will be crowned by archbishops of Mainz. In case that a representative of the Mainz bishopric refused to do so, the Czech monarch would be entitled to choose the bishop to carry out the coronation.

The portrait of Wenceslas I on the obverse side is surrounded by words “Čtyřicetidukát Václava I.“ in the circumscription.

In the upper part of the reverse side, Wenceslas I is depicted in his armour on a fragment of his seal, in the lower part the king with a crown on his head sits on a throne, the latter is a motif from the big bracteate (coin) struck during the rule of Přemysl Otakar I and Wenceslas I.
