A news story about detecting in Canberra. "Metal detectors in hand, they sweep the surface of a small park tucked away in one of Canberra's oldest suburbs. Blip, blip, blip, Neil's device has detected something. Could it be that elusive gold sovereign? Or just another aluminium bottle cap?" http://www.abc.net.au/news/2013-11-15/canberra-backyard-treasure-hunters/5094786?section=act Someone I know told me of a sovereign that was lost, if anyone here finds it please make sure it goes to a good home.
