The vast majority, 96%, were discovered by metal detecting. Norfolk, Lincolnshire, Essex and Hampshire were identified as hotspots for treasure with more than 80 pieces found in each county during 2019. There are approximately 20,000 detectorists in England and Wales, and 348 of their discoveries were acquired by or donated to UK museums in 2019. Of the found treasure, 84% were “object cases”, meaning non-coin finds. – The Guardian
