Принимают ли в Польше рубли?
From 1850, the only currency issued for use in Congress Poland was the ruble consisting of Russian currency and notes of the Bank Polski. The monetary system of Congress Poland was unified with that of the Russian Empire following the failed January Uprising in 1863. However, the gold coins remained in use until the early 20th century, much like other gold coins of the era, most notably gold rubles (dubbed "świnka", or "piggy") and sovereigns. Following the occupation of Congress Poland by Germany during World War I in 1917, the ruble was replaced by the marka (plurals "marki" and "marek"), a currency initially equivalent to the German Papiermark.
