2015 Canada 1 oz Silver $20 Northern Lights The Raven

---

In 2015, the Royal Canadian Mint released a remarkable legal tender coin that merges traditional engraving with modern scientific innovation. Part of a thematic series exploring the lore of the northern lights, this twenty-dollar coin is struck from one troy ounce of highly pure 0.9999 fine silver. The issue is notable for introducing a groundbreaking minting technique, representing the first time the mint employed a non-circular achromatic hologram to bring a design to life. The reverse of the coin features an artistic rendering by Nathalie Bertin, depicting a raven soaring gracefully over a forest of conifers clinging to a mountainside. Above the bird, the sky is transformed by nanotechnology. This specialized application creates a holographic effect that mimics the shifting, ethereal glow of the aurora borealis. Surrounding this central image are the bilingual inscriptions "THE RAVEN" and "A STORY OF THE NORTHERN LIGHTS" alongside their French equivalents, "LE CORBEAU" and "LÉGENDE DES AURORES BORÉALES." On the obverse, the coin displays the right-facing portrait of Queen Elizabeth II. This side also bears the monarch's name, the Latin abbreviation "D. G. REGINA," the issuing nation "CANADA," the year "2015," and the face value of "20 DOLLARS." With a restricted mintage of only 8,500 pieces, this proof-quality coin stands as a fascinating intersection of avian art, folklore, and high-tech physics.
