The Australian 20 cent coin was first introduced with decimalisation on 14 February 1966 when it replaced the pre-decimal Australian florin, to which it is equal in size and mass. The original reverse design by Stuart Devlin has not been changed since its introduction. The denomination is occasionally used by both the Royal Australian Mint and the Perth Mint to issue collector coins, which are legal tender in Australia - such as this one. The 2008 design was developed in partnership with Geoscience Australia - a peak body for International Year of Planet Earth activities in Australia. The reverse of the 20 cent piece features powerful images of tsunami, floods, plate movement and salinity reminding us of the impact geological issues have on our survival. This coin was issued in the 2008 International Year of Planet Earth mint sets only. No coins of this type were issued into circulation. | ||||||
