 The Free City introduced only its own coins and continued to use the banknotes of the Congress Kingdom of Poland.The Kraków złoty was equivalent to the Polish in the Russian-controlled Congress Kingdom, which had a fixed exchange rate to the Russian currencies of 1 kopeck = 2 grosze, or 0.15 ruble = 1 złoty.Following the annexation of Kraków by Austria in 1846 the Kraków złoty remained in circulation until the end of 1847 when it was replaced by Austro-Hungarian gulden.
