2012 Australia $30 Thirty Dollars Silver Proof Queen Elizabeth II Diamond Jubilee One Kilo - Reverse
1952 - 2012
A half price commemorative coin.
The Royal Mint's One Kilo Silver Proof Olympic coin costs £3,000 from the Mint.
Their Diamond Jubilee one is "only " £2,600; which sounds like a bargain, until you see that this Australian equivalent, which is at least as nice, costs under half the price!
