Cloth Seal, Cloth Worker's Personal Seal, Initialled, ER

Cloth Seal, Cloth Worker's Personal Seal, Initialled, ER, Image & Found by Paul Jones.
Found in Bassettlaw, Nottinghamshire, 15mm, 5.4g.

Blank // ER

The ER is not thought to be for Edward Rex or Elizabeth Regina as the seal does not to be an official state one. It has been included in the initialled cloth workers' personal seals section despite its size and style being outside the norm.

As a guess I would place it as from the 15th to 17th century.
