From the Perth Mint...

Australian high relief silver proof strikes are rapidly becoming a popular collecting genre.
This is confirmed by the early interest in the first ever
Australian Kookaburra 1oz high relief silver proof coin, released at the beginning of May. Already, very nearly half the total mintage of 10,000 coins has been shipped in response to strong worldwide demand.
High relief silver coins were introduced by The
Perth Mint in 2010 with a Tuvalu release commemorating the story of
Pheidippidis -- the ancient Greek who ran 25 miles to Athens with news of his army#8217;s historic triumph at the Battle of Marathon.
It was followed by a special Australian commemorative issue portraying Josiah Wedgwood's historic
Sydney Cove Medallion, an extremely significant artefact made from clay found near Sydney Cove in 1788.
Subsequently, we've focused on high relief coins from some of our most popular silver series. Not surprisingly, the high relief 1oz silver proof Dragon from this year's Australian Lunar series was a major international success #8211; with a limited mintage of 7,500 coins, it sold out rapidly!
Later this year in July we will release our third 1oz Australian Kangaroo high relief silver coin. The series got off to an outstandingly successful start in 2010 with a popular release that is no longer available from the Mint. However, anyone thinking about beginning a collection of high relief issues should not overlook the
2011 Kangaroo coin with its superb kangaroo design.
The undoubted interest these coins have already generated have put the high relief concept firmly on our agenda and we're working on new projects that will make for some exciting announcements in the future.
