2013 Australian Antarctic Territory Aurora Australis 1oz Silver Proof Coin

The Tenth coin from this very popular series features the Aurora Australis.

An aurora occurs when charged particles emitted from the sun interact with Earth's magnetosphere. The solar particlwes stream towards the poles, colliding with atoms of nitrogen and oxygen in the upper atmosphere.

Akin to the process that operated in a neon light, the collisions create glowing gases seen as dancing ribbons and arcs of mesmerising light comprising thousands of colours.

The coins design depicts a snowfield with a tracked vehicle and a human observer beneath a coloured representation of the Aurora Australis, which has been coloured with glow in the dark ink

This 1oz silver proof coin struck by the Perth Mint is housed in a blue-coloured presentation case, which comes within a stylish outer shipper.
