The second Estonian kroon currency was introduced in 1992, after Estonia gained independence from the USSR. The kroon was subdivided into 100 cents (senti; singular sent). The one kroon coin was a popular circulating denomination; there was also a banknote with the same value, but the banknote was only issued in 1992 and was rarely used, as opposed to the coin.
These first 1 kroon coins (issued in 1992, 1993 and 1995) were made of copper-nickel (75% copper, 25% nickel); however, due to their similarity to the German one mark, this type was discontinued and they were demonetised on 1 June 1998. Later 1 kroon coins were made of "Nordic gold".
