This week the British Museum unveiled the discover - made by a group of amateur detectorists - of more than 2,500 coins dating back to the Norman Conquest in 1066, including coins minted under the reigns of Harold II and his successor William the Conqueror.
It's the biggest discovery of Norman-era coins for almost 200 year - and the second largest ever - and while the source of the coins is unknown they were likely buried for safekeeping.
In the collection are three illegal ''mule'' coins - with both monarchs' images on each side - which was a way of ''dodging'' fees owed to the crown.
