2016 - $20 - 1 oz. Pure Silver Coin – The Universe: Glow-in-the-Dark Glass with Silver Fume

People have looked to the stars for millennia. It wasn't until the 1930s, though, when scientists who wanted to expand their knowledge of the universe began to listen to them instead. This coin features British Columbia's DRAO, the largest facility of its kind in Canada. When viewed in the dark, this coin reveals a glowing, star-filled sky that even shines through its glass globule, a unique embellishment that was handcrafted in Canada.
