In 2009, the demonetization of the 1 and 2 cent coins was made official and a new coin set of 5, 10, 20, and 50 cent coins with reduced size were introduced. The old coins based on the Australian size standard were withdrawn from circulation. The reformed coins were introduced to save on production costs. The new 50 cent piece is also round with reeded edges rather than twelve-sided. On 2 March 2011, it was announced that Fiji would drop Queen Elizabeth II from its coins and notes, instead opting for local flora and fauna. The removal was seen as retaliation for Fiji's suspension from its full membership of the Commonwealth. The new set, which was unveiled on 12 December 2012 and was issued on 2 January 2013. The new series of Fijian coins include a bi-metallic (brass-plated steel) $2 coin intended to replace the note, and a thinner, reduced weight $1 coin. The new series of Fijian dollar banknotes feature Fijian flora and fauna to replace the portrait of Queen Elizabeth II. One change in the redesign of the Fijian dollar banknotes was the $5 note. Originally printed on paper, it is now issued as a polymer banknote.
