The Perth Mint of Australia, on behalf of the New Zealand Mint has struck a limited edition coin to celebrate the 50th anniversary of Doctor Who.  The Two dollar coins are 99.9% pure silver proof and feature an engraved image of the TARDIS on one side with a stylised time vortex background.  The other side features a familiar portrait of Queen Elizabeth II.  Included on the outer circumference of the coin is the text 'Doctor Who 50th Anniversary 1963 - 2013'.

With no more than 10,000 to be minted, each coin comes with its own certificate of authenticity, packaged in a special presentation case shaped like a TARDIS.  The case makes the classic 'vworp vworp' sound effect when opened to reveal the coin.  Curiously, whilst this commemorative coin for a long-running British science fiction show is being minted in Australia for the New Zealand Mint, it will actually be legal tender in the tiny South Pacific island nation of Niue.

The coin is currently priced at £62.79 (just short of 63 times the face value of the coin in Niue) and can be ordered from the Perth Mint, where there is also tantalising mention of an upcoming eleven coin set featuring each of the Doctor's incarnations so far.
