Work has already begun to raise money to keep the newly discovered Staffordshire Hoard artefacts in the county.
Archaeologists found more gold and silver items in a field near Hammerwich after it was ploughed recently.
Now South Staffordshire coroner Andrew Haigh has ruled that 81 of the 91 pieces were treasure.
Eight pieces were discounted as “modern”, while another two which were found 40 to 50m away from the other items were not part of the Hoard.
Staffordshire County Council leader Philip Atkins admitted they were working with other organisations to try and raise funds to purchase the new artefacts.
“It is great news that more pieces of the Hoard have been discovered,” he said. “The challenge now is to work with our partners to raise the money to make sure the collection stays together in the West Midlands.”
Many of the newly unearted items weigh less than a gram – but the collection does include a possible helmet cheek piece, a cross- shaped mount and an eagle-shaped mount.
