A Yorkshire archaeological site has artefacts from the ninth century, including silver coins including a silver Baghdad coin, and the fragments of two swords. Known as the Ainsbrook Hoard, it is regarded as one of the most important Viking discoveries ever made in the UK. Unfortunately metal detectorists made the major discovery and over the course of many years had sold thousands of the finds and destroyed much of the archaeology. The exact context of those finds is not yet known. The trove was found in a ploughed riverside field, whose location is not being made public. The finds are typical of the personal treasures for use in the afterlife found in Scotland, Ireland and mainland Europe but not previously in England. A collection of clinch nails, used on Viking longships, is the strongest clue to it being a ship burial.
