The National Bank of Poland has launched sales of collector banknotes with a face value of 20 zlotys, commemorating Poland's late president Lech Kaczyński, who died in the Smolensk plane crash in 2010, along with 95 others. Long queues have formed at NBP branches, as they also offer special 500-zloty coins with the president's likeness. Collectors can also buy the items online, but the prices are much higher than at the counter.
