Inscriptions identify the 12 months of the Gregorian calendar and the seven days of the week. In the center is a stylised, pad-printed colour representation of the solar system. The coin is the first in a five-year 'Evolution' series.The individual coin was limited to an issue of 1,500, housed encapsulated in a black, free-standing display case with a clear perspex screen. In addition, the coin was included in two sets: 350 in 4 coin proof sets and 400 in 3 coin proof sets released by the Perth mint.
The Perth Mint commissioned glass artist Elizabeth Mavrick to create 100 Glass Art pieces. One of very few Australian artists working with dichroic glass, Elizabeth has created two versions to complement the coloured design of the ten ounce silver coin incorporated in each piece.
The first design - 'Abstract' (left)- makes extensive use of dichroic glass to capture elements of the coin in an abstract or minimalist way. The brilliance of the dichroic glass in light clearly shows why it is considered to be the king of glass materials. Its lustre, refraction and colour palatte offset the difficulties of securing it.
The second design - 'Vivid' (right) - reflects another innovative use of glass and powders to produce vivid colours which complement the coin's celectial imagery. Limited use of dichroic glass adds an eye-catching dimension.
Measuring 300mm x 420mm and weighing 2.6kg, each piece can be displayed as an object d'art or hung as a wall piece.
The Perth Mint produced a limited edition desktop timepiece incorporating the 2002 10oz Evolution of the Calendar coin.
Both the clock and the coin are protected by mineral glass and set in a free-standing, bi-fold, rhodium case in goldtone.
The clock features Swiss movement with the words 'The Perth Mint' and 'Swiss Made' on the dial.
The timepiece is presented in a black, lacquer box accompanied by user instructions and a certificate of authenticity.
