An almost perfect coin, The Perth Mint's 1/0oz silver Koala almost had it all! 99.99% pure silver yet priced very effectively, the coin had something for everybody! First released in 2011, the littlest Koala was an immediate success. And, in that year, to commemorate, the Mint issued this special Berlin World Money Fair version! Housed in a special 2011 Berlin WMF presentation card, only 250 Koalas were made available at the Fair! That is truly a ridiculously small quantity!
