2015 Mint Proof $30 2 oz. Fine Silver Coin - Moonlight Fireflies (Glow-in-the-Dark) Collection Mint State Unlike any coin issued before, the glow effect is in full colour with variable intensity, creating a subdued glow from the moon on the water, a more pronounced glow from the fire in the background, and an intense glow from the fireflies that appear in the foreground. The effect occurs after placing the coin in a light source for 30 to 60 seconds, then bringing it into the dark to experience the sight of luminescent fireflies at a campsite! With an extremely low mintage of just 4,000 pieces, this coin is both a beautiful work of luminescent art and a high quality limited edition collectible. As a pure silver coin struck by the Royal Canadian Mint The entire reverse image by Canadian artist Ervin Molnar combines rich colours and detailed engraving to recreate the beauty of a moonlit night in the Canadian wilderness. Twilight brings tranquility to the forest, where a canoe has brought campers to rest along the shore for the night. There is an added element of magic in the warm night air as fireflies take flight and intermittently light up the darkness. In the foreground, two fireflies can be viewed up close and in great detail, with colour recreating their delicate wings and markings along their abdomen. But the full effect of the coin is best viewed in the dark after placing it in a light source; photo-luminescent technology transports the viewer into the coins campsite by recreating the only sources of light: the enchanting spark of light emitted by the fireflies, along with the campfires amber flames and the bright full moon that are reflected on the still surface of the water.
