, the others in aluminum-bronze. However, in 1997, nickel-plated steel 20 senti were introduced, followed by aluminum-bronze 1 kroon in 1998. 5 senti coins were not issued after 1994 but were still legal tender. The cupronickel 1 kroon coins from 1992, 1993 & 1995 stopped being legal tender on 31 May 1998. The 5 krooni coins were commemorative pieces and were rarely seen in circulation.
