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 five krooni coin was used as a circulating commemorative denomination only twice, in 1993 and in 1994. A banknote of the same value was preferred though, so the coins did not circulate much.
Just like the second type of 1 kroon coins, they were made of "Nordic gold" - an alloy with composition of 89% copper, 5% aluminium and 5% zinc and 1% tin.
The coins circulated until 15 January 2011 when they were demonetised and replaced with the Euro, when Estonia joined the Euro currency.
