Metal detectorist finds 19th century Japanese coin in Australia

Popular Science

The discovery likely dates back to the continent's gold rushes. Breakthroughs, discoveries, and DIY tips sent six days a week. A metal detector hobbyist discovered a centuries' old coin while scouring an abandoned sports field--and the coin is especially rare for the area. In the southern Australian province of Victoria, treasure hunting enthusiast Angus James recently spotted a well-preserved 100 Mon Tenpō Tsūhō, a 19th century Japanese coin likely deposited during Australia's decades' long gold rush. "You never know what you'll find next," James posted to social media on January 25th, along with photos of his recent haul.
