Builder Richard Mason was suitably underwhelmed when he dug up a grubby looking pot during a house renovation on Lindisfarne.
The 38-year-old from Rothbury, in Northumberland, threw the pot in the back of his van and thought no more of it.
The jug was left in Mr Mason's father's basement for eight years and then one year before Christmas, Richard decided to clean the jug.
He tipped it up and out fell a pile of gold and silver coins.
The coins come from all over Europe and one of them was found to be a gold scudo, a coin made in Italy in the 1500s.
