The Croatian currency is the Kuna, which is divided into 100 lipas. (The word "Kuna" means marten, a weasel-like animal, whose fur Croats used for payment many centuries ago. The lipa is a lime tree, but we dont know the connection here!) When listed as a price, the Kuna is abbreviated to Kn.
The Kuna comes in dominations of 5, 10, 20, 50, 100, 200, 500 and 1,000 as notes and 1, 2, 5, 25 as coins. The Lipa comes in coins of 1, 2, 5, 10, 20 and 50.
