2015 Canada 1 oz Silver $20 Butterfly Giant Sulphur

---

This striking 2015 silver coin from Canada showcases a remarkable blend of traditional engraving and modern color technology. Crafted from one troy ounce of 99.99 percent pure silver, the reverse of the coin captures a delicate moment in nature, portraying a Giant Sulphur butterfly (Colias gigantea) as it drinks nectar from the blossom of a wild strawberry. The insect is rendered with a special light-reflective paint that brings its vibrant coloration to life against the polished silver background. On the obverse, the coin displays the right-facing portrait of Queen Elizabeth II, alongside the year of issue and the face value. Backed by the Canadian government, this twenty-dollar denomination piece was produced with a limited mintage of 10,000 specimens, making it a fascinating study in how mints can combine natural history with advanced artistic techniques.
