A metal detectorist is celebrating today after a rare example of England's 'first ever gold coin' he discovered in a field sold for a world record £648,000.
Michael Leigh-Mallory, 52, was left in shock at the result of the auction of the King Henry III penny that was struck in about 1257.
The coin, which is just under an inch in diameter, was unearthed on farmland in Hemyock, Devon, last September.
