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 senti coin was the smallest denomination issued into circulation (coins with values lower than 5 senti were never made); the first coins which were issued were back-dated 1991.
The coins are made of Aluminium-bronze, with composition of 93% copper, 5% aluminium and 2% nickel.
They issued in only three years - 1991, 1992 and 1995; additional striking and issuing of the denomination was officially stopped on 1 January 1997, but the existing coins were not withdrawn and remained in circulation.
These coins circulated until 15 January 2011 when they were demonetised and replaced with the Euro, when Estonia joined the Euro currency.
