Cloth Seal, Alnage Seal, Rose & Sun joined, Image & Found by Andya.
Found in Hampshire.
Fragment - First side has the sun and rose halved and joined under a crown and the second side has crown over ornate shield with the arms of England from 1406 - 1603 (with gaps), rose (missing) and sun to sides.
Geoff Egan, 'Lead cloth seals and related items in the B.M.' (B.M.occ.papers 93), shows an alnage seal from Bristol, No.4 Fig.8 that exhibits the crown over rose and sun halved and joined and quotes North to tie this symbol in with the dates 1471 - 90 through its appearance on coins. Egan also shows three seals Nos.110, 111, & 113 Fig.25 with the same 'crown over ornate shield with the arms of England, rose and sun to sides' that he dates to late medieval "perhaps the last quarter of the fifteenth century".
Cannot be tied to a place of issue but definitely an alnage seal and, if the use on coinage of the rose and sun halved and joined (1471 - 90) is paralleled on cloth seals then it was issued in the reign of the last monarchs of the House of York (restored) or Henry VII (Tudor).
