The 2 krooni banknote (2 EEK) is a denomination of the Estonian kroon, the former currency of Estonia. Karl Ernst von Baer, who was an Estonian Baltic German anthropologist, naturalist and geographer (1792–1876), is featured with a portrait on the obverse. The 2 krooni bill is called sometimes a "kahene" meaning "a two".
A view of Tartu University which was founded in 1632 is featured on the reverse. Before the replacement of the EEK by the euro, the 2 krooni banknote was the smallest denomination most commonly used by Estonian residents on an everyday basis. It can be exchanged indefinitely at the currency museum of Eesti Pank for €0.13.
