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 and green aurora borealis is the first to go into circulation. The coins use a special ink to illuminate the northern lights about 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.
The mint is not new to creativity or innovation. In 2004, Canada was the first country to have colored coins.
