Cloth Seal, Norwich, Tubular, Disc Type, Image & Found by Axel Vroling.
Found in the Netherlands, 20mm.
LII in pellet oblong // blank
The Roman numerals suggest these match the usual tubular cloth seals from Norwich but these have cut flaps to give a disc-like structure in the same manner as similar Colchester Dutch weavers' tubular seals - see BSG.CS.00114, which shows both the normal tubular and disc version for Colchester.
