From a distance we could see a man on the bridge repeatedly tossing a weighted line into the river below. It didn’t look like fishing, or crabbing. Sampling the water?  Curiosity got the better of me. It turns out he was ‘magnetic fishing’ which is essentially treasure hunting under water. He had a strong magnet at the end of a long piece of cord, and was tossing this from the bridge into the river, hoping to pick up something metallic and valuable.  This was his first outing with his new piece of equipment.

Interestingly he also used a metal detector in fields and had recently found a Roman coin from the 3rd century AD. The coin, which is only the second coin to be found of the emperor Proculus, is being auctioned in London on April 10th 2013 and has been valued at about £80,000.  

Have your say! (No need for any ID!)
