A masterwork of full-colour minting, forming a unique tribute to the dazzling natural phenomenon known as ‘Nacreous Clouds’ or ‘Mother-of-Pearl Clouds’, we are delighted to present the Perth Mint-struck Mother-of-Pearl Clouds 2025 $1 1oz Silver Proof Coin!

An extremely rare, mesmerising optical phenomenon occurring in the polar regions, Mother-of-Pearl Clouds are known as such due to their vivid and often iridescent colours. Forming at high altitudes at extremely low temperatures, they are seen largely over Antarctica, but sometimes over Scotland, Alaska and countries in Scandinavia. To behold Mother-of-Pearl Clouds is to witness nature at its most awe-inspiring.
