Comment
Issued by the RAM in a coincard. This 2022 $1 NCLT Uncirculated Coin commemorates when 100 years ago the eyes of the world were focused on an expedition of international and Australian scientists to Wallal, Australia where conditions would be ideal for photographing a total eclipse due on 21 September 1922. The photographic images taken during this ground-breaking expedition allowed for the precise measurements of the apparent position of the stars near the eclipsed Sun giving scientists the evidence proving Albert Einstein’s revolutionary Theory of General Relativity as correct!
