Półtorak (lit. one-and-a-halfer) was a small coin equal to 1½ grosz struck in Polish–Lithuanian Commonwealth in the 17th century, during the reign of Sigismund III Vasa and John II Casimir Vasa. Initially a silver coin, with time its value deteriorated and the coin went out of use. Augustus III of Poland unsuccessfully tried to reintroduce it as a copper coin. The name stems from the Polish word "półtora" meaning one and a half.
The coin was introduced in 1614 due to the need to strike a popular coin between a grosz and a trojak (3 grosz coin). From its early days, the półtorak was a coin of relatively low value, manufactured of impure silver (grade 0.469). Intended as a coin to be used close to the borders of the Kingdom of Poland, the coin's silver content was kept low to prevent valued metals from leaving the country. Initially produced at the Cracow mint, it was also produced in Bydgoszcz and between 1619 and 1620 also in Vilna.
