The exhilarating
spectacle of Mother of Pearl Clouds lights up the sky in all its
opalescent glory on this one troy ounce pure gold proof, made all the more desirable by
the ultra-low mintage of just 99! Truly rare, a pair of fur seals
gazes skyward to admire this rare and vibrant phenomenon.
This masterwork of digital minting captures the atmospheric phenomenon known as Mother of Pearl Clouds. Struck in one full troy ounce of pure gold, this frosted cameo proof depicts two friendly fur seals on an ice floe gazing skyward at these nacreous clouds, as they are also known. These iridescent natural wonders hold both us and the seals mesmerized with a kaleidoscope of opalescent color.
The spellbinding occurrence of Mother of Pearl Clouds shows the skies ablaze with awe-inspiring colors and vibrant hues. Most will never be able to see this extremely rare event of the high Arctic and Antarctic winters in person, but now you can possess this precious metals prize yourself. This beauty looks even better in hand than in the mint-supplied images!
As rare as it is beautiful, the Mother of Pearl Clouds Gold Proof has a mintage limit of just 99! All previous releases in this series have sold out at the mint. We expect the same for this gem.

Nacreous Clouds
A mother of pearl cloud is a polar stratospheric cloud (PSC). Also known as a nacreous cloud ("nacre" is another name for mother-of-pearl), it forms in the winter polar stratosphere at altitudes from 15,000 to 25,000 m (49,000 to 82,000 ft). As such, it is extremely rare, far more difficult to experience than the Aurora Borealis and Aurora Australis (the northern and southern lights).
Mother of pearl clouds are best observed during twilight, when the Sun is between 1° and 6° below the horizon, as well as in winter and in more northerly latitudes. One of the two main types of PSC consists only of ice crystals. This type of PSC is also called nacreous, from nacre, or mother of pearl, due to its iridescence.
The stratosphere, where these rare and unusual clouds form, is very dry. Unlike the troposphere, it rarely allows clouds to form due to this dryness. In the extreme cold of the polar winter, however, stratospheric clouds of different types may form, which are classified according to their physical state (super-cooled liquid or ice) and chemical composition. Due to their high altitude and the curvature of the surface of the Earth, these clouds will receive sunlight from below the horizon and reflect it to the ground, shining brightly well before dawn or after dusk.
Type II clouds, which are very rarely observed in the Arctic, have cirriform and lenticular sub-types, and consist of water ice only. Only Type II clouds are necessarily nacreous, whereas Type I clouds can be iridescent under certain conditions, just as any other cloud.

Niue
Niue is a small island nation in the South Pacific. Although it is completely self-governing and independent, it remains in free association with New Zealand, a member of the British Commonwealth of Nations, hence the portrait of the British monarch on most of its coinage. The country is located about 1,450 miles northeast of New Zealand. It is closest to Samoa, Tonga, and the Cook Islands. It is one of the largest coral islands in the world, with a total area of 260 square kilometers. Niueans are predominantly Polynesian; most are bilingual, speaking both Niuean and English.
