Thirty years ago, a farmer found a few Iron Age silver coins while working on his land in the island of Jersey, off the coast of Normandy. Now, after combing the soil with metal detectors for three decades, two treasure hunters have found a hoard of silver and gold coins, the biggest of its kind, valued at $15 million.Text from Gizmodo; see also Yahoo.

The treasure was inside a large block of clay. It contains 30,000 to 50,000 silver and gold Celtic coins dating from the 1st Century BC.

They have been buried for more than 2,000 years. According to numismatic experts, each coin is worth 100 to 200 British Pounds ($156 to $311).

Caesar describes his encounters with the coastal tribes of the area he called Armorica in The Gallic Wars...
...the Veneti, the most prominent of the Armorican tribes, along with their Armorican neighbors captured some of Caesar’s officers to exchange them for hostages the Romans had taken... When they fled to the sea, Caesar had his troops build ships, but they couldn’t compete with the locals’ heavy navy and sailing expertise in the treacherous waters of the Channel and Atlantic.
He did it in the end, though. He destroyed the Veneti fleet using giant billhooks to sever the lines used to hoist the mainsails. With the sails on the deck, the Celtic ships were entirely out of commission. They couldn’t even row because the huge sails cloaked the deck. Caesar then went from coastal town to coastal town and killed everyone...
