Poland uses the złoty, which have been in circulation since the 14th and 15th centuries. The złoty will not be around for too much longer since Poland will eventually adopt the euro.
Out of all of the bills, the 5000 zł note is my favorite. Why you ask? Because Chopin is on it! How OG is that? He is also on a commemorative 2010 20zł note.
The most recent series (1994) of the Złoty bill include the denominations of 10, 20, 50, 100, 200 (rare)
