A gold Anglo Saxon shilling was found by Paul Flack whilst using a metal detector on farm land in Mildenhall in February this year, an inquest was told.
Faye Minter, senior finds recording officer with Suffolk County Council’s Archaeological Service, said the coin had been modified for usage as a pendant and dated from around 660-680AD.
She said: “The coin has been pierced and the remains of a separately cast cylindrical silver rivet are present towards one side of the flan, indicative of modification for usage as something other than a coin.
Dr Peter Dean, Greater Suffolk Coroner, ruled that the coin should be considered as treasure.
It is understood that the Norwich Castle Museum and Art Gallery were interested in purchasing the item. Its value will be decided by an independent committee of experts.
