Canada is rolling out new glow-in-the dark coins to celebrate the country's 150th birthday. The Royal Canadian Mint says a two-dollar "toonie" that features a view of the blue-green aurora borealis is the first to go into circulation. The coins use a special ink to illuminate the northern lights above two canoeists paddling along a remote lake. Other luminescent coins depict similar scenes of Canada's natural wonders. There's also a collectors' coin featuring Canada's red and white maple leaf flag with exploding fireworks overhead.
