The General Assembly of the United Nations has declared 2008 the "International Year of Plant Earth".
The aim of the year is to demonstrate new and exciting ways in which Earth Sciences can help future generations meet the challenges involved in ensuring a safer and more prosperous world.
The Royal Australian Mint has recognised the importance of this Year in its 2008 coin designs for the $1 and 20 cent piece. The Royal Australian Mint's designer, Vladimir Gottwald, chose images of ground water and geological processes for the $1 coin featured in this proof quality set.
This set is housed in a rigid plastic case which is enclosed in a leatherette folder bearing the Royal Australian Mint/Australian Government badge on the front. The folder is housed in a colourful outer shipper with information booklet.
