Täpsemalt
The first Koala in this series was released in 2007. It featured one kilo of .9999 fine silver and became an instant hit. Admired for its elegant design and beautiful finishes it became vastly popular among investors and collectors alike. This coin is also praised for holding a face value that is backed by the Australian government.
Each coin's reverse includes a security feature in the form of a micro-laser engraved letter within the coin's "AUSTRALIAN KOALA" heading. It is only detectable under a magnifying glass.
