Not a Cloth or Bag Seal, Document Seal, Plantagenet

Plantagenet Document Seal, Image & Found by Philthy Phil.
Found in Warwickshire.

From the finder:- "Plantagenet document seal... having pooled my knowledge of the local history of the manor site where the seal was found and the heraldic expertise of the Lancaster Herald we've managed to acertain that the seal is certainly Plantagenet and "probably" late 13th-14th century and "probably" was a seal on the original documentation granting the lands to 'John of Gaunt, Duke of Lancaster, whose son King Henry IV gave it in 1410 to the Dean and Chapter of Newark College, Leicester, for a chantry of two priests for the souls of his parents.'

The reason for the 3 lys in the bottom right quarter but 6 in the top left is simply that at that time it was customary to fill the space and so as the top left quarter was larger it took more lys to fill it! The opposite of "less is more" I guess."
