Item Description:

In 1922, the eyes of the international scientific community were focused on an expedition of scientists to Wallal, Western Australia to photograph a total eclipse due on 21 September.

Precise measurements of the apparent position of the stars near the eclipsed Sun were photographed and provided the evidence supporting Einstein's revolutionary Theory of General Relativity.

To celebrate the centenary, the Royal Australian Mint have struck an uncirculated aluminium bronze $1 and a domed shape, $5 silver proof.
