On the 15th of November, amateur historian Edward Hynes found a coin dating back 600 years ago in Newfoundland, Canada. According to CNN “ The discovery of a rare gold coin on the south coast of Newfoundland, Canada, may challenge traditional historical narratives about the timing of European contact in the region. It predates explorer John Cabot’s arrival on the island by at least 70 years.” The government keeps the location where it was found a secret to discourage potential treasure hunters. According to CNN, the coin predates the first European contact since the Vikings.
