Cloth Seal, Crowned E O, Image & Found by Derfel.
Found in the City of London, 20 x 16mm,

Two part cloth seal. Possibly a clothiers seal but also has a continental look to it. Another possible attribution is to Colchester - previous Thames foreshore find.
Distinctive markings should lead to eventual identification.
